Each bulb produces 70 lumens and uses an E26 medium screw base, making it a potential match for common medium-base sockets. The listed 120V, 60Hz operation and claimed maximum life of up to 15 years are notable for a decorative replacement, although actual service life depends on usage conditions, voltage, switching frequency, and the quality of the connected string set.

The main limitation is brightness. At 70 lumens, this option may produce a gentler effect than some of the 100-lumen S14 alternatives in the guide. The product information also does not state that it is compatible with solar string lights, so buyers should not assume that support based on its outdoor and waterproof characteristics.

This is a sensible choice for a patio, courtyard, terrace, party, wedding, bar, restaurant, or indoor decorative installation that uses E26 sockets and favors a soft, romantic glow. It is especially attractive for shoppers who want a warm retro appearance, a shatterproof body, and a long advertised service life without moving to a high-output design.

Warm Lighting for Decorative Spaces

The 2200K color temperature creates a notably warm atmosphere that works well for intimate outdoor dining, parties, and accent lighting. At 70 lumens, it favors ambience over intense illumination, making it most suitable when the bulbs are one visible layer of a larger lighting plan.

Built for Outdoor String Sets

The listing identifies the bulbs as waterproof and shatterproof, useful attributes in exposed patios and gardens. Because the connected string-light assembly also affects protection, shoppers should verify that the existing cable, socket, and weather rating are suitable for outdoor use.

2. Meconard 24 Pack S14 LED – Best Budget Warm Glow

4.7Editor scoreCheck price on Amazon

Meconard 24 Pack S14 LED

120V, 1 watt

Hundred lumens output

E26 medium base

Twenty-four bulb pack

The Meconard 24 Pack S14 LED is a strong all-around replacement for standard E26 string-light sockets. It has a 4.7 rating and pairs a vintage Edison-style shape with 100 lumens of warm-white light, giving it more visible output than the lower-lumen options without moving beyond the familiar 1-watt LED format.

Pros

• Strong 100-lumen output
• Shatterproof plastic housing
• Weather-resistant construction
• Long 25,000-hour life
• Good indoor-outdoor versatility

Cons

• Not for solar string lights

We may earn a commission when you buy through this link, at no additional cost to you.

Its clear plastic housing is designed to resist impacts, snow, rain, extreme temperatures, and harsh sunlight. The listed operating life of up to 25,000 hours also makes it a practical choice for frequently decorated patios, gardens, bistro areas, camps, and parties. Installation is straightforward because the E26 medium screw base fits standard compatible fixtures.

The important limitation is solar compatibility: the manufacturer explicitly advises against using these bulbs with solar string lights. No dimmability is specified, so buyers who want adjustable output should not assume that a wall dimmer or built-in string control will work. As with many screwed-in bulbs, a dark socket may sometimes need a tighter connection.

This pack is a good value-oriented pick for anyone replacing a group of conventional S14 bulbs on a 120V outdoor set. It offers one of the stronger brightness figures in the guide, a generous count of 24, and a warm appearance suited to patios and gardens. Verify the socket, voltage, and dimmer requirements before ordering.

A Practical Outdoor Balance

The 1-watt LED specification and 100-lumen output create a useful balance between brightness and energy use. The product is designed to replace an 11-watt incandescent bulb while retaining the decorative character of traditional filament lighting.

Shatter Resistance for Active Areas

Unlike fragile glass bulbs, the clear plastic shell is intended to withstand drops and exposure to demanding outdoor conditions. That makes it more suitable for patios, gardens, restaurants, and party spaces where accidental impacts or temperature changes are plausible.

GvvooHome 24 Pack S14 LED

Dimmable LED output

E26 medium base

Weatherproof plastic shell

Twenty-four bulb pack

The GvvooHome 24 Pack S14 stands apart with dimmable operation, making it a flexible option for buyers who want control over the brightness of an E26 string-light installation. Its 4.6 rating indicates favorable feedback, and the warm-white S14 styling suits gardens, balconies, terraces, and indoor wedding-party decorations.

Pros

• Adjustable dimmable output
• Shatterproof clear housing
• Weather-resistant design
• Flicker-free illumination
• Two-year warranty

Cons

• Not for solar string lights
• Dimming requirements not detailed

We may earn a commission when you buy through this link, at no additional cost to you.

The high-clear plastic shell is described as drop-resistant and less vulnerable to dangerous fragments than glass. The product information also states resistance to rain, wind, and extreme temperatures, along with flicker-free, UV-free, IR-free, mercury-free, and lead-free operation. A two-year warranty adds a visible manufacturer commitment to buyers.

Dimming is the key qualification. The listing calls the bulbs dimmable, but it does not explain whether compatibility depends on a particular dimmer, string-light controller, or electrical setup. It also explicitly says not to use the bulbs with solar string lights. Those points should be checked before purchase, especially in a professionally planned installation.

Choose this product when you use standard E26 sockets and want a vintage-inspired, dimmable glow without resorting to glass bulbs. It is a good fit for restaurants, terraces, backyards, event spaces, and indoor decorative lighting, provided the string set supports the required dimming method and is not solar powered.

Flexible Light for Changing Moods

Dimmable output lets a single string set move from a brighter accent to a softer evening atmosphere. This is particularly useful in dining areas, event venues, and patios where the same installation serves several lighting needs.

A Safer Alternative to Glass

The shatter-resistant clear shell preserves the open decorative appearance associated with glass Edison bulbs while reducing the risk of sharp fragments. It is a sensible construction choice for exposed household and commercial spaces.

4. Meconard 25 Pack G40 LED – Compact Globe Warmth

4.6Editor scoreCheck price on Amazon

Meconard 25 Pack G40 LED

E12 candelabra base

One-watt LED output

Eighty lumens per bulb

Twenty-five bulb pack

This Meconard G40 set is intended for string lights and decorative fixtures that use the smaller E12 candelabra or C7 socket. The 25 bulbs measure approximately 1.57 inches in diameter and produce a warm retro glow, making them appropriate for outdoor sets, chandeliers, sconces, and other visible fixtures.

Pros

• Compact 1.57-inch globe
• Fits E12 and C7 sockets
• Shatterproof plastic body
• Energy-efficient LED design
• Versatile indoor-outdoor use

Cons

• Not for solar string lights
• Lower output than 100-lumen bulbs

We may earn a commission when you buy through this link, at no additional cost to you.

The product has a 4.6 rating. Each LED consumes 1 watt and is described as equivalent to a 5-watt incandescent bulb, with an output of 80 lumens and 80 percent energy efficiency. Its clear plastic globe is more impact-resistant than glass, which is useful for outdoor installations and high-traffic decorative areas.

The primary compatibility issue is the socket. E12 and C7 bulb shapes may look similar but are not interchangeable with the E26 medium base used by most S14 products. These bulbs are also not suitable for solar string lights. Dimming is not listed as a supported function, and the manufacturer advises tightening bulbs securely if one does not illuminate.

This is the right option for shoppers replacing small globe bulbs in a candelabra-base string set. It combines a classic appearance, low heat dissipation, and broad indoor-outdoor versatility in a 25-bulb pack. Confirm the socket marking and bulb diameter before buying to avoid a mismatch.

The Right Shape for Smaller Sockets

The G40 globe is a visual and functional alternative to the longer S14 bulb. Measure the existing bulb and check the socket type before purchasing, because an E12 or C7 fixture cannot accept a standard E26 replacement.

Efficient Retro Globe Lighting

Warm-white filament-style LEDs recreate the look of antique incandescent bulbs while using less power and producing less heat. The result suits decorative fixtures where the glowing filament and classic globe shape are important parts of the design.

5. GvvooHome 48 Pack S14 LED – Best Premium High-Count Design

4.6Editor scoreCheck price on Amazon

GvvooHome 48 Pack S14 LED

IP65 waterproof rating

Dimmable 2200K output

E26 medium base

Forty-eight bulb pack

The GvvooHome 48 Pack S14 is the most substantial replacement supply in the guide and is positioned for larger installations, multiple string sets, or owners who want a ready reserve of bulbs. Its 4.6 rating is supported by a feature set centered on adjustable 2200K light, PET construction, and an IP65 waterproof rating.

Pros

• Largest bulb count included
• Adjustable warm illumination
• IP65 waterproof rating
• Durable PET construction
• Twenty-thousand-hour lifespan

Cons

• No dimmer included
• Not for solar string lights

We may earn a commission when you buy through this link, at no additional cost to you.

Every bulb uses 1 watt and is described as equivalent to an 11-watt incandescent bulb, with an advertised lifespan of up to 20,000 hours. The 2200K color is especially appropriate for patios, bistros, backyards, and everyday decorative use, while smooth dimming allows the atmosphere to be adjusted. A dimmer is not included, so buyers must provide a compatible control if they want variable output.

IP65 protection is a meaningful specification, but it applies to the bulb rather than automatically to the entire string assembly. The listing specifically tells shoppers to confirm the waterproof rating of the string lights in which the bulbs are installed. The bulbs are also not compatible with solar string lights, an important limitation for buyers of solar-powered systems.

This is the pick for a larger E26-based installation where extensive replacement coverage matters. The 48-bulb count reduces the need for repeated orders, and the combination of dimmability, warm color, shatter-resistant PET plastic, and IP65 protection makes it a premium choice for patios, bistros, and outdoor entertaining areas. Confirm dimmer and string compatibility first.

A Larger Replacement Buffer

Forty-eight bulbs can cover several substantial runs of medium-base string lights. That makes the pack practical for property managers, event venues, restaurants, and households that want spare bulbs on hand without ordering repeatedly.

IP65 Protection with Clear Limits

The IP65 rating supports use in demanding outdoor conditions, including exposure to rain, snow, heat, and wind. It does not replace the need for a suitably rated string-light cable and socket system, which must provide the actual environmental protection.

6. FLSNT 15 Pack S14 LED – Best Editor's Choice Warm Style

4.7Editor scoreCheck price on Amazon

FLSNT 15 Pack S14 LED

2200K warm white

E26 regular base

One-watt LED output

Fifteen bulb pack

The FLSNT 15 Pack S14 offers a balanced mix of warm styling, practical outdoor construction, and straightforward installation. Its 4.7 rating is among the highest in the guide, while the 2200K color and Edison-style appearance make it well suited to patios, porches, gardens, lawns, gazebos, and entertaining areas.

Pros

• Clear shatterproof plastic housing
• Warm Edison-style appearance
• Simple E26 installation
• Broad outdoor application
• Low-heat LED operation

Cons

• Non-dimmable design
• Modest 15-bulb count

We may earn a commission when you buy through this link, at no additional cost to you.

The clear plastic bulb housing is described as shatterproof and waterproof, with high light transmission intended to resemble a conventional glass bulb. A 1-watt LED consumes less energy than the listed 5-watt incandescent equivalent, produces lower heat dispersion, and provides high lighting efficacy. Installation requires only a compatible E26 regular screw base and power disconnected beforehand.

This model is explicitly non-dimmable, so it is best for shoppers who want consistent brightness rather than adjustable output. Its 15-bulb count is also smaller than the 24-, 25-, 36-, and 48-bulb alternatives. Nevertheless, for a single patio, porch, or modest garden run, that quantity may be more than sufficient.

Choose this option when you want a recognizable warm Edison appearance in a shatterproof E26 bulb. It is a particularly sensible pick for weddings, restaurants, bistro areas, bars, front porches, and pergolas, as long as the string set accepts non-dimmable 1-watt bulbs and you do not need dimming controls.

Classic Glow Without Fragile Glass

The high-transmittance plastic shell recreates the visible glow of a glass bulb while avoiding the most obvious breakage concern. That balance of appearance and resilience suits exposed outdoor installations and frequently handled decorative fixtures.

Wide Range of Outdoor Settings

From lawn weddings to restaurant patios, the warm light is versatile enough for residential and commercial settings. Its 2200K output creates a relaxed amber-white atmosphere that works especially well for social and decorative areas.

Jslinter 24-Pack S14 LED

Sixty lumens per bulb

E26 medium base

Minus twenty to forty Celsius

Twenty-four bulb pack

The Jslinter 24-Pack S14 is a durable, warm-white option for E26 medium-base patio lights. It carries a 4.7 rating and combines a shatterproof plastic shell with a stated operating range of minus 20 to 40 degrees Celsius, making it a practical choice for seasonal outdoor string-light use.

Pros

• Impact-resistant plastic housing
• Long 25,000-hour life
• High switching-cycle rating
• Cool-to-touch operation
• Warm 60-lumen glow

Cons

• Not compatible with E12 bases
• Lower brightness than 100-lumen options

We may earn a commission when you buy through this link, at no additional cost to you.

Each 1-watt LED produces 60 lumens at 2200K. The listing compares it with an 11-watt incandescent bulb, says it saves more than 90 percent on lighting electricity, and states that it remains cool to the touch. Its claimed service life reaches 25,000 hours, with support for 300,000 switching cycles and six hours of listed aging.

The brightness is lower than the 80- and 100-lumen options, so this set is better for a subtle decorative effect than strong task-style illumination. It also cannot be used with E12, C7, or C9 candelabra sockets. As with other screw-in products, fit and electrical compatibility remain more important than the bulb's general description.

Choose it for patios, gardens, and other E26 string sets where a soft, inviting glow and long advertised life matter more than maximum brightness. It is a solid middle ground for homeowners and commercial operators who want resilient construction, low heat output, and a 24-bulb supply at the same time.

Engineered for Repeated Switching

A high stated switching-cycle figure suits installations that are turned on and off frequently rather than left running continuously. Combined with the long lifespan claim, it makes the product relevant to seasonal and year-round decorative use.

Soft Output for Atmospheric Lighting

At 60 lumens, the light has a gentle decorative character. It is best suited to creating a warm pool of ambiance along a patio, garden path, seating area, or outdoor dining space rather than illuminating a large work area.

8. G40 Clear Incandescent Bulbs – Authentic Clear Globe Glow

4.7Editor scoreCheck price on Amazon

G40 Clear Incandescent Bulbs

120V, 5-watt rating

E12 candelabra base

One-and-half-inch globe

Twenty-five bulb pack

The G40 Clear Incandescent set is the only traditional glass-and-tungsten option in the guide. It is aimed at owners who want the familiar appearance and warm glow of incandescent bulbs in a clear 1.5-inch globe that fits C7 and E12 candelabra sockets. Its 4.7 rating indicates strong customer satisfaction within that specific use case.

Pros

• Clear glass globe styling
• Traditional filament appearance
• E12 and C7 compatibility
• Simple screw-in installation
• Padded individual packing

Cons

• Uses more power than LEDs
• Glass is vulnerable to breakage

We may earn a commission when you buy through this link, at no additional cost to you.

Every bulb is rated at 120V and 5 watts for indoor or outdoor decorative lighting. Installation requires no tools beyond screwing the bulb into a compatible empty socket. The product information also says the globes do not strobe, and each bulb is packed in soft pearl wool to help protect it from damage during transportation.

The trade-off is efficiency and fragility. Incandescent bulbs consume more electricity and produce more heat than the LED alternatives, while the glass globe can shatter if dropped or struck. These factors make the set less attractive where low power use, child or pet safety, or frequent handling is important.

Choose this product when maintaining a traditional incandescent string set, matching an existing warm aesthetic, or matching a fixture that is not designed for LED bulbs. It works for gardens, balconies, terraces, and outdoor gatherings, but buyers should check the fixture's voltage, wattage limit, and socket type before installation.

Classic Decorative Character

The clear glass globe and tungsten construction deliver the uncomplicated vintage appearance many traditional string-light owners prefer. It can be easier to preserve an existing look than to introduce a visibly different LED bulb shape or light quality.

Mind the Glass and Wattage

Because the bulbs are made from glass and consume 5 watts each, they require more care than the shatterproof LED choices. Check the socket's maximum wattage and avoid using a bulb with a rating higher than the fixture permits.

Meconard 36-Pack S14 LED

E26 medium base

One-watt warm LED

2200K color temperature

Thirty-six bulb pack

The Meconard 36-Pack S14 provides a generous supply of warm-white replacements in the widely used E26 medium-base format. It has a 4.7 rating and uses resilient plastic bulbs designed to restore the appearance of vintage incandescent lighting while avoiding some of the fragility associated with glass.

Pros

• Large 36-bulb supply
• Shatter-resistant plastic housing
• Cool operation
• Vintage filament appearance
• Easy standard-base installation

Cons

• Not for solar string lights
• Dimming support not stated

We may earn a commission when you buy through this link, at no additional cost to you.

Each bulb consumes 1 watt and is described as delivering brightness equivalent to an 11-watt incandescent bulb. At 2200K, the light has a warm, inviting tone suited to indoor string lights, outdoor patios, gardens, and entertaining areas. The plastic construction is intended to resist drops and impacts, and the low-energy operation keeps heat output to a minimum.

These bulbs are not for use with solar string lights, and no dimming capability is specified. A bulb that fails to illuminate after the string is plugged in may simply need to be tightened further, so contact continuity and correct seating should be checked before assuming a bulb is defective.

This is a good pick for a large E26 installation, multiple string sets, or households that want a healthy spare supply. The 36-bulb count offers useful coverage without reaching the scale of the 48-bulb option, while the warm 2200K output remains well suited to patios, dining spaces, and decorative indoor installations.

Ample Bulbs for Multiple Runs

Thirty-six bulbs can cover several medium-base strings or provide spares for future failures. That makes this pack useful for event operators, property owners, and anyone who would rather avoid replacing individual bulbs throughout the season.

Warm Filament Style with Resilience

The 2200K glow recreates the inviting look of traditional filament lighting, while the plastic body improves drop resistance. It offers a practical middle ground between the fragile appearance of glass and the long-lasting efficiency of LED.

VISTERLITE 25 Pack ST38 LED

E12 candelabra base

One watt, 2200K

Weatherproof PET housing

Twenty-five bulb pack

The VISTERLITE 25 Pack ST38 is a distinctive bulb choice for candelabra-base string lights that call for a slim Edison-style shape. Its 4.6 rating and 2200K warm-white output make it a solid option for patios, gardens, pools, bedrooms, and event spaces where atmosphere matters.

Pros

• Distinctive ST38 torpedo shape
• Shatter-resistant PET plastic
• Flicker-free warm light
• Indoor-outdoor versatility
• Mercury and lead free

Cons

• Not for solar string lights
• Only E12 or C7 compatible

We may earn a commission when you buy through this link, at no additional cost to you.

The product describes the bulb as an ST38 torpedo-style Edison bulb, with listed dimensions of 3.25 inches tall by 1.5 inches wide. It uses a C7/E12 candelabra base and consumes 1 watt. The housing is made from durable PET plastic intended to resist drops, wind, and impacts while providing a shatter-resistant alternative to glass.

The product is also described as waterproof and flicker-free, with no mercury, lead, UV, or IR emissions. It is not compatible with solar string lights, and its E12/C7 base rules it out for E26 sockets. Because the shape differs from a round G40 and a standard S14, existing shade or socket clearance should be checked before purchase.

Choose this set for a candelabra string set that uses long decorative bulbs and a romantic warm glow. It works well for poolside entertaining, garden dining, bedroom accents, and patio parties, offering a more sculptural look than a standard globe while retaining efficient LED operation and weather-resistant construction.

A More Sculptural Decorative Shape

The long ST38 profile creates a recognizable torpedo silhouette that can complement vintage-inspired installations. Its warm light and narrow decorative form are particularly effective when the bulbs remain visible beneath umbrellas, pergolas, awnings, and patio canopies.

Weather-Resistant Construction

PET plastic is intended to withstand drops and outdoor exposure without the breakage risk of conventional glass. As with any outdoor bulb, the surrounding string-light assembly, connectors, and sockets must also be suitable for the environment.

Buying Guide – How to Choose the Best Replacement Bulbs for Outdoor String Lights

The right replacement begins with the socket and bulb shape, but voltage, wattage, weather exposure, light output, and control methods also determine whether a bulb will work safely and look right. Use the following factors to narrow the options before checking current product details and availability.

Confirm the Socket Base

The base must physically and electrically match the socket. E26 is the medium screw base used by most standard S14 string lights, while E12 and C7 are smaller candelabra bases commonly found in G40, ST38, and other decorative bulbs. A bulb that looks similar may still have a different thread diameter, contact design, and voltage requirement. Consult the original string-light instructions, inspect the socket marking, or compare the replacement with a removed bulb before ordering.

Choose the exact base specified for your set: E26 for medium-base models and E12 or C7 for candelabra models. Never force a bulb into an uncertain socket.

Match the Bulb Shape

Shape affects both appearance and physical clearance. S14 bulbs have a small, tapered Edison-like profile, G40 bulbs are round globes, and ST38 bulbs are longer torpedo shapes. Replacing a globe with a narrow bulb can alter the visual balance of a string, while installing a larger bulb in a shade may create heat buildup or inadequate clearance. Check the original bulb dimensions and the distance between the socket and any shade, canopy, or cover.

Match S14 to S14 sets, G40 to compatible globe sets, and ST38 to matching torpedo-style fixtures whenever possible. Visual consistency is as important as electrical fit.

Verify Voltage and Wattage

Most of the listed products operate on a nominal 120V system, but the exact rating of the existing string set remains the controlling factor. A bulb with too little voltage may not light properly, while one with too much wattage can exceed what the socket or fixture was designed to handle. For LED replacements, it is especially important to confirm that the string set is compatible with the lower LED power draw and that any dimmer or controller is designed for LEDs.

Use only a replacement whose electrical specifications align with the string-light instructions. If the equipment is solar powered, note that most LED options in this guide expressly exclude solar string lights.

Consider Light Output

Output ranges from 60 lumens for the Jslinter S14 set to 100 lumens for the Meconard 24 Pack S14. Lower output usually creates a softer decorative mood, while a higher lumen rating provides a more visible glow. Because bulb design, clear plastic transmission, diffuser construction, and string spacing all affect the result, lumen ratings should be compared within similar bulb formats rather than treated as a guarantee of total brightness.

Choose around 60 lumens for a relaxed accent and consider 80 to 100 lumens for a clearer decorative presence. Avoid judging fit or appearance from brightness alone.

Select the Right Color Temperature

Most options use warm-white LED light, and many specify 2200K. That lower color temperature produces a golden, nostalgic appearance that works well on patios, dining areas, garden paths, and event spaces. The G40 incandescent option naturally provides a warm glow as well, but its light characteristics and energy use differ from the LEDs. If the original set mixed colors or used a more neutral bulb, replacing only a few bulbs with a different temperature may be noticeable.

For a consistent appearance, match the existing bulbs' color temperature and style. A 2200K warm-white replacement is the most common choice for a cozy outdoor look.

Evaluate Outdoor Protection

A bulb may be described as waterproof, weatherproof, or weather-resistant while the complete string-light system still needs appropriate protection. The 48-bulb GvvooHome set has an explicit IP65 rating, while several other products describe resistance to rain, snow, extreme temperatures, wind, or sunlight. Socket covers, cable integrity, connectors, and the fixture's own outdoor rating determine how the installation performs as a whole.

Prioritize shatter-resistant plastic for exposed areas and verify the complete fixture's weather rating. Never assume a waterproof bulb makes an indoor-rated cable safe outdoors.

Check Dimmability and Controls

Only the GvvooHome 24 Pack S14 and the dimmable 48-bulb GvvooHome S14 are explicitly identified as dimmable. The FLSNT set is explicitly non-dimmable, and the remaining listings do not establish dimming compatibility. LED bulbs may also require a dimmer designed for LED loads, and some string sets use proprietary controls that ordinary wall dimmers cannot operate.

Check the instructions for both the bulbs and the string set before buying. If dimming is important, confirm the required control method and obtain a compatible dimmer separately.

Plan for Pack Size and Spare Bulbs

Pack counts range from 15 bulbs to 48 bulbs, so the right quantity depends on the number of active sockets, the condition of the existing set, and how many spares you want. A smaller pack may suit one patio run, while a 25- to 48-bulb pack can cover multiple installations or several seasonal decorating projects. It is also sensible to retain unused bulbs in a dry place and replace them if they no longer match the original set's color or brightness.

Count the sockets before ordering and add a small reserve for future failures. Larger packs are particularly useful for commercial displays and frequently decorated outdoor areas.

How to Use and Care for Your Replacement Bulbs for Outdoor String Lights

Begin by switching off and unplugging the string-light set. If it is connected to a solar system, confirm that the replacement bulbs are compatible before installing them; several products in this guide expressly do not support solar string lights. Compare the replacement with the original bulb to verify the base, shape, voltage, wattage, and any dimming requirements.

Remove one old bulb at a time and screw the replacement into the empty socket by hand. Do not force it, overtighten it, or use a tool that could damage the threads. Seat the bulb securely, restore power, and check the entire run. If an LED remains dark, unplug the set and tighten it slightly, since a poor contact is a common installation issue.

Clean the bulbs with a soft, dry cloth and keep the sockets free of dirt and moisture. Inspect the cable, seals, and connectors for cracking or corrosion, especially after severe weather. Store spare bulbs in a dry, protected place, and replace the complete string if its insulation, plugs, or sockets show damage rather than trying to compensate with a new bulb.
