Features to know about

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

This compact 3/4" round light uses a single amber LED that lasts up to 50 times longer than traditional incandescent bulbs. With a low power draw of just 0.052 amps at 12V, it delivers bright, clean light without putting a strain on your electrical system. There are no fragile filaments or bulbs to replace—just reliable illumination that keeps working trip after trip.

Built for Wet Conditions: Sonically Sealed and Submersible

No need to worry about water getting in and ruining your light. The polycarbonate housing and lens are sonically sealed together to form one solid unit, making it fully waterproof. Whether you’re launching at the boat ramp or driving through wet roads, this submersible design keeps the diodes and circuit board protected from moisture.

Better Visibility and Coverage: PC-Rated 180-Degree Beam Pattern

Seeing and being seen matters most on the road. This PC-rated light throws a 90-degree spread to either side of its centerline for a full 180 degrees of visibility. When properly mounted, it functions as both a clearance and side marker light, so others can spot you head-on or from the side even in low-light conditions.

Tight Spaces Made Simple: Compact Recessed Mount with Grommet

Space can be limited, but installation doesn’t have to be complicated. This recessed-mount light fits neatly into a 3/4" hole using the included grommet. The 2-wire pigtail setup—one power lead and one ground—keeps wiring straightforward. At just 15/16" thick, it tucks cleanly into place without sticking out where it could catch on anything.

Durable by Design: Polycarbonate Lens and Housing

Made with a tough polycarbonate base and lens, this light stands up to vibration, impact, and everyday use. It’s designed for longevity in harsh environments while maintaining a clear amber glow that stays bright over time. And with a lifetime warranty on the LEDs, you know it’s built to last.

Beautiful tail light. Very bright for the brake and turn signal. Fitted it on the back of my trailer with an L bracket.

Perfect fit, tinned leads these should last a while! The original lights on my boat trailer only last five launch and retrieves.

Just what I needed for side lights on my trailer



by:

It was hard to find information regarding the replacements for lamps in my Forest River MH. I only found the info on etrailer. I was reluctant to replace my slightly larger originals which began flickering with these which have a center on-off button. I ordered a couple from etrailer. The replacemets worked fine, were easy to replace. All remaining originals began to fail. I then ordered enough to replace all originals and replaced all originals when they failed. Replacements are still working fine. If your's begin to fail, consider ordering enough to replace all of your lights. Slight size difference is not noticeable from my slightly smaller originals. Individual on-off buttons can be a benefit but might be confusing to next owner because my lights also turn on off by named regions on a separate control.



by:

Super clean look. Installed these on my boat trailer that just went through a complete restoration.



by:

Just what I needed and arrived in a quick time. Thank you



by:

Easy to use but if they could be about 2-3" longer, it would be very helpful.

These work well and I havent had any issues with them. Still rate them 4 stars only because the tails should be longer. Otherwise 5 stars.

@Jasonf I am glad to hear that they are still working well for you at least! I appreciate that feed back on the tails, I will definitely pass that along. What kind of trailer did you replace these on?


by:

I'll let you know when I install



by:

Fits and works as expected. I thought there were tinned for marine use and better corrosion resistance.
