This small light packs a serious punch. The single red LED puts out a bright, clean light that’s far more efficient than any old incandescent bulb. At just 0.052 amps on a 12V system, it barely sips power while giving off excellent visibility. You never have to worry about replacing bulbs or dealing with fragile filaments again—the LED lasts up to 50 times longer, so once it’s in, it’s good for the long haul.
If your trailer ever hits the water, this light is ready. The housing and clear lens are sonically sealed into a single waterproof unit, keeping moisture out completely. That means the diode and circuit board stay protected even when submerged. It’s a dependable choice for trailers used in wet or harsh environments where water damage usually kills lesser lights.
Visibility matters for safety, and this PC-rated design delivers a full 180-degree beam pattern. Mounted properly, it works as both a clearance and side marker light—bright from the front and sides alike. That wide spread of light helps make your trailer more visible from different angles at night or in low-light conditions, keeping you safer on the road.
Sometimes space is tight, and this compact 3/4" diameter light fits right in. It installs flush with the surface using the included grommet for a clean, finished look. The 2-wire pigtail keeps wiring simple—one line for power and one for ground—and the durable polycarbonate housing holds everything securely in place. Whether replacing an old unit or adding new lighting, installation stays straightforward and neat.

Ryan: Hey everybody. Ryan here at etrailer. Today, we're going to be taking a look at and showing you how to install the Optronics LED Clearance and Side Marker Light. The first thing I noticed about this light is that it is very bright, even in a well lit room like we're in today. It's really tough to even look at. It's almost going to hurt your eyes if you stare at it too long.
It's going to throw that light 180 degrees, so no matter what angle you're at, you're going to be able to see it illuminated. That's really going to give you a little more peace of mind knowing that, not only at nighttime but also in the daytime, people are going to see your trailer. And what makes it so bright is the fact that it's an LED. These LEDs are much more reliable and longer lasting than the traditional style incandescent bulbs and much brighter.We're getting all this light from one small LED, so that sure beats a really large incandescent bulb that we have to worry about breaking and replacing. The LED style, you know it's going to work and should last for a very long time.
What's really nice about this too, is that the light is going to be really small in size. We're going to have a ton of different options on where and how we mount it up to our trailer. And because it is small, you're not just limited to trailers. Some guys like to put these on their side by sides, their four wheelers, their mud trucks and so on. We really do have a lot of versatility with this setup.
It's kind of cool. Whenever we turn the light off, it's going to have a clear lens. And to me, compared to the regular style orange lenses, I think the clear one just kind of blends in a little bit better and gives us more of a modern look.But really at the end of the day, it's just going to be which type you prefer. At the end of the day, a light that you know is going to work and you really can't go wrong with. Now, as far as the installation goes, it's really straightforward.
There is only two wires we're going to need to hook up. It shouldn't take you hardly any time at all. Speaking of which, let's go ahead and do that together now.If you just kind of hold the light in your hand, right away the first thing that I can tell is that it's pretty well built. Everything feels really solid. The casing is nice and hard. I think it'll last a long time. If we flip it over and look at the back, there is some sealer inside of there, which is going to make this light submersible. However, I do suggest if you do completely submerse this, to at least turn the power off to it, just to be on the safe side. It's going to have a sheathing that runs along the wire here to help keep them in good shape, and what kind of separates this one is the length of wire. It gives us a ton of wire to work with. That way, if you don't have a ton to work with on the trailer side, this is going to kind of make up for that and make life a little bit easier when you're trying to get it hooked up.It is also going to come with the grommet that you need. This will slide over your wires and into your trailer. That way your light can plug into it. I'm not going to push it all the way down on there, because it is a little tricky to get off, but you get the idea. And that's nice, just one less thing you're not going to have to worry about picking up separately or have to worry about reusing your old beat up one.Now, just to make sure this will work with your setup, I'll give you a few measurements. The diameter of the light is going to be three quarters of an inch. The length of it, or the depth, is going to be fifteen-sixteenths of an inch. And if you're curious, the length of the wire is going to be 14 inches long.To begin our install, we're going to be here at the corner of our trailer, where we're going to put our light in right here. First thing you're going to want to do is take the grommet and push it into place. Straightforward, this just pushes right in. Once we have it in there, we'll take our light, take the wires, slide it through. We'll push that light into the grommet, just like that. And then, we can focus on hooking up our light wires to our existing trailer wires. What we're going to do to get that done is use heat shrink butt connectors. These aren't included, but you can pick them up here at etrailer. I'll just slide the bare end of the wire into the butt connector. Cramp it down.Same thing for our white light wire here. The white wire coming out of our light is going to be for a ground. That's where this existing trailer wire goes. That gets plugged in, crimped down. And our black trailer light wire is going to be the power wire. We'll hook that into our existing trailer wiring here. Crimp it down. And since these are heat shrink butt connectors, I'll come in with my heat gun to seal up the ends.Before we kind of clean up our wiring, I'm going to put power to the trailer, that way we can make sure our light works. We turn it on. It's illuminating as it should. What I'll do now is clean up our wiring and then show you what it looks like once I have that done. And this is what our light looks like secured. I just used some zip ties to hold it up in place. You will need to pick those up separately. You can find them right here at etrailer. But other than that, if you have a light for the other side, you'd simply just repeat this same process over there. And that'll finish up our look at and our installation of the Optronics LED Clearance and Side Marker Light..
Ratings & Reviews
Easy ordering, fast shipping, fair price... what more could you ask for?
Super fast shipping. Product was as described and works perfectly as replacements on my motorhome. Very happy with this experience.
I bought the led lights over a year ago and even with MI winters and all the road salt the are still working perfectly. Great product you won't go wrong buying them.
Ordered the LED trailer pucks. They came really quickly, and the bonus was they already had dielectric grease on the female contacts and ready to install. I was pleasantly surprised.
I thought yall were just trailers , was not aware did boat as well, thanks deliver in great shape
The lights went on easy with one positive wire and ground. Being led makes it brighter than my old lights
Had trouble tracking these specific lights down online. I have bought a few things from etrailer before and they always deliver exactly as advertised. These are a direct replacement for the lights that I had which seemed impossible to find!
The light works excellent. Unfortunately after I took the old one off I realized that the original was never wired up correctly from the factory lol. New light is much brighter so I might go ahead and replace the other two. Received very quickly.
These Optronic LED lites were exactly what I was looking for my boat trailer. Easy install and very bright. Good product and quick shipping. I highly recommend this company.
Works great
Nice and bright also seems of good qual ity
Bright light for it's compact size.
Product is spot on, fit finish and function. More importantly the whole ordering/delivery process worked to perfection. Our company was in a tight jam with one of our transport trailers and needed these lights pronto,
e-trailer came to our rescue and didn't even know it. That in itself proves that customer service is
e-trailers top priority.
Ordering was easy. Processing was immediate. Shipment was prompt. Light fit as advertised and works perfectly. Many thanks.
Great product
Fast delivery decent priced
This is the second one of these lights I’ve installed on my trailer, and no issues so far!
