SEALIGHT 3157 LED Bulbs 2PC — 6000K 1800LM White Reverse & Brake Light Upgrade, Plug-and-Play

SEALIGHT 3157 LED bulbs are a high-output, plug-and-play replacement for 3157/3057-style reverse, tail and brake lights that deliver crisp 6000K white illumination at 1800 lumens each.

If you're upgrading aging incandescent bulbs or adding brighter reverse and brake lighting for better visibility, these SEALIGHT LEDs provide a modern, efficient option. They use 3030 SMD diodes, an intelligent IC driver and aircraft-grade aluminum housing to combine bright output with dependable thermal control. The bulbs are non-polarity and sized to match common halogen bases, so installation is typically straightforward on compatible sockets.

How bright are these bulbs compared to stock halogens?

Each SEALIGHT 3157 LED produces about 1800 lumens and a 6000K color temperature, which reads as a clean white light. That makes them substantially brighter than standard halogen filament bulbs, improving visibility when reversing or signaling. Brightness is achieved while keeping power draw low, typically around 8W per bulb.

• 1800 lumens output per bulb for strong illumination
• 6000K crisp white color for clear contrast
• Low power consumption at roughly 8W each

Will these fit my vehicle’s 3157, 3057, or similar sockets?

The SEALIGHT 3157 design is compatible with many two-contact bayonet-style sockets including 3157, 3057 and a number of related numbers listed in vehicle manuals. Because vehicle trim and housing space vary, double-check your original bulb type before ordering. The non-polarity wiring simplifies installation, so orientation isn't usually an issue.

• Fits 3157, 3057, 3156, 3056 and other common equivalents
• Non-polarity for easier swap-in replacement
• Confirm original bulb number in your owner’s manual for exact fit

What materials and features keep these LEDs durable?

SEALIGHT builds these bulbs with aircraft-grade aluminum to improve heat dissipation and extend service life. An intelligent IC driver protects the LEDs and helps ensure consistent performance across 12–24V systems. The combination of high-quality components and built-in thermal control aims to provide many years of use under normal driving conditions.

• Aircraft-grade aluminum body for efficient cooling
• Intelligent IC driver for voltage management and reliability
• Estimated long lifespan when installed in appropriate housings

Do I need extra adapters, resistors, or wiring changes?

Most installations are plug-and-play thanks to the bulb’s matching base and non-polarity design, so extra parts are often unnecessary. Some vehicles with CAN-bus or hyper-flash monitoring systems may require load resistors or a decoder to prevent error messages or rapid blinking. Check for dash warnings after installation and add resistors if your vehicle signals a bulb fault.

• Typically plug-and-play with matched bayonet base
• CAN-bus vehicles may need resistors or decoders
• Verify no dashboard errors after replacement

Who this is for: drivers who want a brighter, whiter, energy-efficient upgrade for reverse, tail or brake lights and who have compatible 3157/3057-style bulb sockets. It’s ideal for car owners replacing dim or failing halogen bulbs, fleet vehicles needing reliable visibility, and DIYers looking for a straightforward swap. If your vehicle uses a CAN-bus system or has limited housing space, confirm compatibility before purchase to ensure proper fit and operation.
