Features to know about

Upgrading to LED for Brighter, Longer-Lasting Light

This Optronics Double Bullseye LED clearance or side marker light uses 10 amber LEDs that shine bright while drawing very little power—only 0.087 amps at 12.8V. LEDs last 50 times longer than incandescent bulbs and don’t have fragile filaments to break, so you won’t be dealing with burnt-out bulbs anymore. The result is a clean, efficient light that improves visibility and reliability every time you tow.

Better Visibility from All Angles: PC-Rated Coverage

With its PC rating, this light delivers a wide 180-degree beam pattern that can be seen from the front and the side. When mounted properly, it functions as both a clearance light and a side marker light, giving your trailer better visibility in low light and at night. That added coverage helps make sure others see you coming and going.

Simple Surface Mount Design for Easy Installation

At 4-1/16" long x 2-1/8" wide x 1-1/8" deep, this rectangular light installs flat against the trailer surface without cutting any holes. It uses a surface-mount flange with 3" center-to-center mounting holes. The 1-wire self-grounding design makes wiring straightforward—just connect the power lead and mount the light to a metal surface to complete the circuit.

Durable Polycarbonate Build That Holds Up Over Time

The rugged housing and snap-on amber lens are made of durable polycarbonate that resists cracking and wear. Even after years of vibration and exposure, the lens stays clear and secure. It’s built for consistent performance wherever your trailer goes, backed by a lifetime warranty on the LEDs.

Distinctive Double Bullseye Look That Stands Out

The unique double bullseye lens design gives this light a recognizable style while helping focus the LED output evenly across both lenses. It’s not just functional—it looks great too, adding a clean, modern touch to your trailer lighting setup.

look good.. haven't installed them yet.. only a 18 gage wire so we'll see..



by:

Lights are of excellent quality, and were packaged with care. Arrived pretty fast as well.



by:

You can not ask for anything better than how they delivered the products I ordered in a timely fashion...excellent selection & service



by:

Bright and uses less power. Fits within chrome metal guard snugly ;) very satisfied



by:

Delivered fast and is exactly what I wanted.
Time will tell if the last on my boat trailer



by:

The product arrived on time and in good condition. The replacement product was as described and works well. The vendor was very easy to work with and kept me updated on all aspects of the transaction. I would have no problem recommending them. All in all, a positve experience.



by:

Exactly what I needed. Thank you!



by:

I am using them for turn signal lights on a new trailer I pull behind my trike. They work great.



by:

The product itself is good as always. I do wish on the other-hand that someone would have called or emailed me when there was a duplicate order. I now have double what i need and yes etrailer was able to get me return info but its a pain in the ass to get it returned for me.



by:

very bright, works well



by:

Replacing incandescent marker/ clearance lights with LED. These items were easy to find on the website, the order process was smooth, shipping was quick, and install super easy. As long as they last as they should this is a no brainer. First time using etrailer.com, definitely won’t be my last!



by:

The lights are exactly as advertised. Very bright. I had previously replaced the incandescent bulbs with led bulbs which was an improvement but these are at least twice as bright as that. Also the back of the fixture has a hollow space that allows for the fact that the original wires were in a different location than on these. Therefore very easy to install.



by:

Products are what they, I find eTrailer sells quality items. More impressive is the customer service. I've just completed my 4th order and have consistently received above average customer service. I've utilized both email & phone to resolve issues (issues that were totally if my own doing) & the response was timely & professional. I will be sure to continue using eTrailer & furthermore will definitely recommend them to others



by:

Great quality light. Is install and super bright. Would buy again.



by:

Did not realize how much I missed having the light when trailering at night. Very bright!

Still working on trailer.



by:

A great upgrade for my old trailer that had a single run wire for everything. It was intimidating at first, but having the instructions right next to the unit it wasn't too difficult to figure out. I only wish there was a way to turn off battery charging without disconnecting the whole DC, so when i'm running off the battery, it's not trying to also charge it



by:

Installed LED trailer lights. They work well, easy install. Night and day difference
from old lights. Recommend switch to LED.

Still working as expected, no issues at all



by:

Far better than alternatives. Specifically the raised lip on the back of the lights allowing for the single wire and crimp to lay properly and not sandwich between the panel and the back of the light.



by:

Just what i needed!



by:

Great lights, very bright. As usual, great customer service.



by:

It was the correct light! and was what I wanted, thanks for the fast shipping!



by:

One year later and still nice and bright. No fading or hazing on the lenses. Perfect replacement for the original lights on my Fruehauf/Jartran cargo trailer.
