The Underground lighting 921 T15 Reverse Light bulb is manufactured with four side illumination and a projector lens on top increasing the overall brightness. The aluminum housing distributes heat evenly to maximize the lifespan of the bulb. And the best part is that these bulbs are plug and play so installation is quick and simple.
Illumination. All Underground Lighting LEDs are rated with accurate lumen figures, never calculations or guesses. We test the true output, and provide you with real numbers to compare. At 1000 lumens, the Underground Lighting white backup LED will provide more total light output than a factory incandescent bulb.
Dependability. Unlike other bulbs on the market, this bulb is built with the latest updated aluminum circuit board for quick heat dissipation and better LED chip protection to ensure durability. This bulb will last for years, rather than months, with no flickering or failure. And like every Underground Lighting product, it's backed by our industry-leading two-year replacement warranty.
Expertise. After over a decade in business, Underground Lighting is one of the most trusted names in automotive lighting. We design and manufacture all of our own products to meet our strict quality standards. We pride ourselves in having a knowledgeable staff to deliver superior service that will exceed your expectations. Please contact us if you'd like to discuss your lighting needs.
My old reverse lights were not very helpful when backing up, but with these I can now see!
I am happy with the purchase. The product guarantees efficient lighting for my BMW 335i 09 car. I have used it for reverse lights. And, the lights are not overwhelming at all. No sudden brightness that can cause problem with the back camera. It works well with other lights on my BMW 335i 09 car.
