Features to know about

Brighter, Longer-Lasting, and Efficient: LED Trailer Light

Swapping out old incandescent lights for LEDs makes a big difference in visibility and reliability. This 3/4" round light uses a single red LED that shines brighter while using less power—just 0.052 amps at 12V. With no fragile filaments or bulbs to replace, it lasts up to 50 times longer than standard lights. It keeps your trailer visible without overloading your electrical system, and once it’s in, there’s practically no maintenance needed.

Worrying About Water Damage: Fully Submersible and Sealed

If your trailer sees rain, road spray, or even full submersion, this light is ready for it. The housing and lens are sonically sealed into a single waterproof unit so moisture can’t sneak inside and ruin the diode or wiring. It’s built for tough environments where water resistance really matters, staying dependable whether you’re backing into a wet ramp or hauling through bad weather.

Better Side and Rear Visibility: 180-Degree PC-Rated Coverage

Good lighting isn’t just about brightness—it’s about coverage. This PC-rated light throws a 90-degree beam to each side for a full 180 degrees of visibility. That wide spread means it works as both a clearance and side marker light when mounted properly, helping others see your trailer from more angles in low-light conditions.

Simple Fit Installations: Compact Recessed Mount with Grommet

Space is tight on most trailers, so compact lights make life easier. Measuring just 3/4" in diameter and 15/16" thick, this recessed-mount light installs neatly with the included grommet. It only needs a 3/4" hole to mount flush and clean against the surface. The simple 2-wire pigtail—one lead for power, one for ground—keeps wiring straightforward so you can get it installed quickly and back on the road fast.

Built Tough for Heat and Hard Use: Durable Polycarbonate Construction

This light doesn’t mind heat or heavy use. The polycarbonate lens and housing handle up to 270 degrees before melting, which means it stands up to hot weather and long days on the road without deforming or fading. That same tough build also resists cracking and wear from vibration, making it a dependable choice for lighting you can count on trip after trip.
