SEALIGHT 3157 LED Reverse Light Bulbs, White 2-Pack — 57‑SMD Projector Lens, 700% Brighter

SEALIGHT 3157 LED Reverse Bulbs are high-output, plug-and-play 57-SMD reverse/back-up lights that deliver dramatically brighter white illumination for safer reversing and improved rear visibility.

These SEALIGHT replacement bulbs upgrade standard halogen reverse lights with a focused projector lens and aviation-grade aluminum body to push brighter, whiter light farther behind your vehicle while keeping heat managed and installation simple. Designed to fit a wide range of wedge bases used for backup, brake and tail applications, the bulbs run on 9–30V systems, draw only 6.6W each, and are sold as a convenient two-piece set for quick front-to-back replacement.

How much brighter are these bulbs compared with stock halogens?

SEALIGHT rates these LEDs at roughly 700% higher perceived brightness versus typical halogen bulbs, producing about 1,425 lumens per bulb of white light. Brighter output helps you see obstacles and improves the visibility of your vehicle to others when reversing.

• 57 SMD LED chipset (56×4014 + 1×2835) per bulb
• Approx. 1,425 lumens white light output
• Typical brightness gain: around 700%
• Optimized projector lens for focused beam and reduced glare

Will these bulbs fit my car or truck?

The SEALIGHT 3157 bulbs use a non-polarity wedge design and are compatible with numerous common bases, making them a straightforward swap in many vehicles. They are compatible with both 12V and 24V systems thanks to the 9–30V operating range.

• Compatible bases: 3157, 3156, 3057, 3056, 3155, 3356, 3357, 3457, 3757, 4057, 4114, 4157
• Not compatible with bases: 7443/7440 and 912/921
• Plug-and-play, non-polarity design—no wiring mods in most cases
• Works on 12V and 24V vehicles (9–30V range)

How durable and heat-resistant are these LEDs?

SEALIGHT engineered these bulbs for extended service life using a full aviation-grade aluminum housing and an internal constant-current IC that helps regulate power and reduce stress on the LEDs. The housing and lens arrangement also direct light efficiently to avoid hot spots while assisting heat dissipation.

• Aviation-grade aluminum body for faster heat transfer
• Built-in constant-current IC for stable operation
• Projector lens focuses light and prevents dark spots
• Low power consumption: 6.6W per bulb

How will these bulbs affect my rear lighting setup?

These SEALIGHT bulbs are designed primarily for backup and reverse applications but can serve in brake, tail or parking light assemblies depending on your lamp housing and local regulations. They produce clean white light and the projector lens helps the beam reach farther without causing unnecessary glare for following drivers.

• Common uses: backup light, reverse light, brake light, tail/parking light
• If using as turn signal, housing must be amber or meet local requirements
• Projector lens reduces scatter and concentrates illumination
• Sold as a pack of 2 for pairing left and right bulbs

Who is this for: Drivers who want a brighter, longer-lasting replacement for factory halogen reverse or backup bulbs—especially owners of cars, trucks, SUVs and light commercial vehicles that use 3157-style wedge bases and operate on 12V or 24V electrical systems. These bulbs suit anyone seeking clearer rear visibility when backing up without complex installation or heavy power draw.
