Features to know about

Bright, Efficient Illumination: Low-Draw LED Power

Older incandescent plate lights can be dim, fragile, and power-hungry. This rectangular LED license plate light fixes that with two bright diodes that draw only 0.027 amps at 12.8 volts. You get crisp, even illumination that makes your plate easy to see at night without adding extra load to your electrical system. And since the LEDs last 50 times longer than traditional bulbs, you won’t be replacing burnt filaments anymore.

Reliable in Wet Conditions: Fully Submersible and Sealed

If your trailer ever goes near water, this light is built for it. The housing and clear lens are sonically sealed into a single waterproof unit that keeps moisture out completely. It’s fully submersible, so you can back down ramps or tow through storms without worrying about corrosion or shorted circuits. The sealed design protects the diodes and circuit board for long-term dependability.

Simple Wiring and Mounting: 2-Wire Pigtail Setup

Installing this light is straightforward thanks to the simple two-wire pigtail configuration—one for power and one for ground. It mounts using a bracket or grommet (sold separately), so you can pick the setup that fits your trailer best. The compact size—2-1/2" long x 1-1/4" wide x 13/16" deep—makes it easy to fit in tight spaces while still providing solid plate coverage.

Built to Last: Durable Polycarbonate Construction

Between road debris, water spray, and vibration, trailer lights take a beating. This one holds up with a tough polycarbonate lens and housing that resist cracking and wear. Combined with its sealed LED design, it’s the kind of light you install once and count on for years of clear visibility wherever you haul.

etrailer Shipped the license plate light very quickly. they are very helpful with information about other trailer lighting. I will use etrailer from now on because of their excellent service.

Was working good when I sold my boat



by:

The License plate light mounting bracket (LP25Sb) and the license plate light (LPL91Cb were east to install and work great.
The mounting bracket is heavy duty and the light installs securely inside the bracket.



by:

Had to wait a couple of weeks for one piece on the order to come in, but etrailer let me know what was going on. Product looks good, will install in the next couple of days. 2nd time I've used etrailer, good stuff, good prices, good service.

Still working great, nice and bright.



by:

great lense. I painted the back to get it to shine better on the plate.



by:

Perfect replacement for the old incandescent license plate lights on my 2019 Newmar Mountain Aire. I did paint one side silver to match old lights. These new LEDs lights are sealed so I expect they won’t burn out easily like the old lights.

Thanks for the review Doug, Glad to hear these were a perfect replacement for the incandescent license plate lights. I like the idea of painting one side to match the original lights and I agree, by the lights being sealed they should last a lot longer. Thanks for stopping by and we appreciate you choosing etrailer!
