Keeping your trailer visible from every angle makes a big difference on the road. This amber 2-1/2" round side marker is PC-rated, meaning it shines a full 180 degrees for both side and clearance visibility. The built-in reflector boosts safety even when the light is off, making sure your trailer stands out day or night. Rated for over 100,000 hours of performance, it keeps shining bright trip after trip without the worry of bulb failures.
When lights get wet, corrosion and failure follow. This light is built to stop that from happening. Its polycarbonate lens and housing are sealed together as one piece, and TecSeal urethane potting protects the internal circuitry. With an IP68 rating, it resists water and dust intrusion, so it’s ready for use even in harsh or wet environments where other lights give up.
Sometimes space is limited, and this light fits in neatly without sticking out awkwardly. With a compact 2-1/2" diameter and only 15/16" depth, it mounts cleanly using a standard grommet (TN43TR, sold separately). The flush look keeps things tidy while still giving you the brightness you need for visibility.
Wiring doesn’t have to be a puzzle. The non-polarized PL2 2-pin connector makes installation straightforward—there’s no need to worry about which wire goes where. Running on 9–14 V DC and drawing just 0.068–0.092 amps, it’s efficient and easy to power with your existing setup. Once it’s in, you can count on consistent light output every time you turn your system on.
Road debris and harsh sun can take a toll on lesser lights, but this one’s built from automotive-grade materials designed to last. The polycarbonate lens stands up to impacts and UV rays without fading or cracking over time. Whether it’s long miles on the highway or rough roads near the water, this light keeps performing without showing wear.

Hi everyone, Steven here with etrailer.com. Today we're looking at our TecNiq Round Side Marker Light in amber. This is gonna be a 2-1/2" diameter grommet mounted light, and I do wanna point out that there's no grommet included or wiring. You're simply gonna get the light and the light by itself. So if you need that grommet, it's item number TN43TR sold separately. And I just have this lit up with some demo clips that I'm using today for the studio.
Again, none of this is included, it's just the light itself, no grommet. You should already have the connectors on your trailer. If you don't, it's just two simple, straight pushing connectors that it's gonna use. And again, once it's installed, it's gonna light up whenever you hit your signals, whether it's your clearance light or whatnot. And I do wanna shut off the overhead lights so you can get a better look at this in the dark, so you can kind of see how bright it is.
It's a polycarbonate lens. It's automotive grade built, so it's resistant to UVs and impact rated to all safety standards here in the US and Canada. And the housing protects against dust, water intrusion, and they have what's called a TecSeal urethane potting seal. So that basically protects your circuitry inside of the light itself, giving you long-term durability and performance. And of course, LEDs, as we know, are super bright and they're rated for long, long time, in this case, over a hundred thousand hours of LED performance.
So again, folks, two and a half inch diameter, no grommet included, runs on 12 volts. This is the amber TecNiq Round Side Marker. I'm Steven, thanks for watching.
