When you need strong, wide illumination behind your trailer, this Optronics backup light really shines. It uses 36 white LEDs under a clear lens to produce a bright, even light pattern that makes backing up safer and easier. Rated at 175 candela, it gives you the highest output among 6-1/2" oval LED lights. Each light draws only 0.125 amps at 12.8V, so you get excellent brightness without putting extra load on your wiring system.
Water and vibration are tough on lights, but this one is made to handle both. The polycarbonate housing and lens are sonically sealed into a single waterproof unit, keeping out water and debris. That sealed design makes it a dependable choice for trailers that see boat ramps, rain, or muddy backroads. You won’t have to worry about moisture sneaking in and damaging the circuit board or diodes—this light is built to stay dry inside.
Installing this light doesn’t require any complicated rewiring. It’s designed for a recessed mount using the A70GB grommet (sold separately) and connects with an industry-standard 2-prong plug such as the A45CB (sold separately). The oval shape—6-1/2" long by 2-5/16" tall and 1-13/16" thick—fits perfectly in most recessed cutouts or mounting brackets like the BK70BB. Once it’s fitted, you get a clean, flush look that stays secure over time.
Traditional bulbs burn out; these LEDs don’t. They’re rated to last up to 50 times longer than incandescent lights, all while using far less power. No fragile filaments to break, no bulbs to replace—just steady performance every time you flip them on. The Optronics lifetime warranty on LEDs backs that up, letting you install them once and rely on them for years of service.
Safety standards matter when lighting up the road or ramp. This backup light meets DOT and FMVSS 108 requirements in any 360-degree position when used as part of a two-lamp system. That certification means you can trust it to deliver proper brightness and coverage wherever it’s mounted, keeping your setup visible and compliant every time you tow or reverse.

We have noticed the same. These 36 diode versions are using much older LED technology and have less light output than some of the newer 10 diode models. Part BUL10CB will provide much more light output than this unit, and it even costs less.These older LEDs offered a reduced amperage consumption, but not a brightness increase over their incandescent counterparts. Newer LED technology consumes less and outputs more than the incandescent equivalents.

Remember, DOT regulates how bright a back up light can be. Since Optronics builds this as a back up light, it will not be any brighter than reverse lights are allowed to be under DOT regulations.

The light were just what I was looking for, bright, clean looking and good price.

I have these lights wired to a toggle switch and they still work fine. I would not mind if they were brighter, but they still light up my flatbed well enough that I can hook up a gooseneck trailer in the dark. I have ordered other products from etrailer and the customer service is still great.

Lights have withstood being in the weather all year and still function just as well as they did after installation. Excellent Product.
