SEALIGHT 3157 LED Reverse & Brake Light Bulbs 2PC White 6000K 1800LM Projector Lens

SEALIGHT 3157 LED bulbs are high-output white replacement bulbs for reverse, brake, and tail lights delivering 1800 lumens and a crisp 6000K color in a compact 3157/3057-compatible package.

These SEALIGHT bulbs are engineered as direct-fit LED substitutes for multiple bayonet-style sockets, offering dramatic brightness and improved visibility while drawing just 8W at 12–24V. The integrated projector lens and premium 3030 LED chips create a focused beam pattern suitable for reverse lights, brake lights, and DRL/tail functions. Built from aircraft-grade aluminum with an intelligent IC driver and a non-polarity design, they simplify installation and run cooler than standard halogen bulbs.

How much brighter are these bulbs compared with stock halogens?

SEALIGHT rates these 3157 bulbs at 1800 lumens each and highlights up to 1000% greater brightness over many factory halogens. Brightness is concentrated by a projector lens, which helps produce a sharper, more noticeable white light at 6000K without excessive scatter.

• 1800 lumens per bulb for strong reverse and brake illumination
• 6000K cool white for clear contrast at night
• Projector lens for focused, visible beam pattern
• Lower energy draw: about 8W each at 12–24V

Will these fit my vehicle and how easy is installation?

These bulbs are made to be compatible with many bayonet-style fittings including 3156, 3056, 3057, 3157 and dozens of related part numbers. The non-polarity design removes the need to check orientation during install, so they generally plug in like a halogen replacement; however, confirm your vehicle’s bulb size before purchase.

• Multi-fit compatibility: 3156, 3056, 3057, 3157 and similar bulbs
• Non-polarity: installs without worrying about orientation
• Direct-fit form factor mimics halogen size for simple swap-in
• Check owner’s manual or original bulb to verify size

How do these perform over time and how are they built?

SEALIGHT builds these LEDs on an aircraft-grade aluminum body that acts as an efficient heat sink to extend component life. An intelligent IC driver provides stable power management across 12–24V systems, supporting reliable operation and a claimed long service life when used under normal conditions.

• Durable aluminum housing for improved heat dissipation
• Intelligent IC driver for voltage regulation and reliability
• Low power consumption helps reduce load on vehicle circuits
• Estimated long lifespan when installed correctly

Are there any install or compatibility cautions I should know?

Size and socket variations can differ by vehicle trim—some cars use special housings, resistors, or CAN-bus systems that may require adapters or decoders. Because these are bright 6000K LEDs, ensure the bulb type is appropriate for its intended function (reverse vs. brake) to avoid glare or legal issues in your jurisdiction.

• Verify original bulb size and socket before ordering
• May need load resistor or CAN-bus decoder in some vehicles
• Confirm legal color and brightness for brake and tail use locally
• Some trims/housings can affect final fitment and beam pattern

Who this product is for: Drivers seeking a high-visibility, energy-efficient upgrade for reverse, brake, and tail lights who own vehicles with standard 3157/3057-style sockets. It’s ideal for owners who want a crisp 6000K white light, a focused projector beam, and a plug-and-play replacement without major wiring changes—provided they confirm fitment and local regulations first.
