Tired of bulbs burning out or losing brightness over time? This 3/4" round Uni-Lite uses a single red LED that lasts up to 50 times longer than old incandescent lights. It’s built for efficiency, drawing just 0.052 amps at 12.8V while putting out a bright, clear light through its durable polycarbonate lens. Since there are no fragile filaments or bulbs to replace, you get steady performance and lower power use every time you hook up.
If your trailer ends up in wet conditions, this light is ready for it. The housing and clear lens are sonically sealed into one solid unit, keeping water out completely. That means the LEDs and circuit board stay protected—even when submerged. It’s a dependable choice for trailers that see rain, road spray, or boat ramp launches.
Visibility makes a big difference for safety on the road. This PC-rated light shines with a 180-degree beam spread—90 degrees to either side of center—so it can serve as both a clearance and side marker light when properly mounted. Drivers can see it clearly from the front or side, giving you reliable coverage at night or in low light.
When space is tight, this small round light fits where others can’t. It’s 3/4" in diameter and just 15/16" long, so it tucks in close without sticking out. Installation is simple too—just cut an 11/16" hole for the included black PVC grommet, connect the 2-wire pigtail (power lead and ground), and you’re done. The recessed mount keeps everything neat and secure on the surface.

Hey everybody, Ryan here at etrailer. Today we're going to be taking a look at and showing you how to install the Optronics trailer Light led clearance or side marker light. So right away, the first thing I noticed about this light is how bright it's going to be. It's actually really impressive for how big the light itself is. As you can see, even in a well lit room like we're in today, it's going to have no issues to really throw in that light off far for other motors to see. So really kind of puts your mind at ease, knowing that you're lit up.
Now, it kind of separates this one from some of the other types of lights is that this is the trailer Light. So as you can see, that the light is really dispersed evenly throughout the lens. It gives us a nice, solid light, as opposed to some of the other ones where you can kind of see through the lens itself and just see that one led.With this one it gives us a cleaner and more bright appearance. So what I like too, is the size of the light. It's pretty small.
So it's going to give us a lot of different options on where, how you want to mount it up. Works perfect for trailers like you have today. But also a lot of people are starting to put these types of lights on their mud trucks, their off-road vehicles, like side-by-sides for example, golf cards, things of that nature. So even if you want to mount these up on a different type of project, you're going to be able to find a spot to put them.So once we have the light turned off, we're going to have a solid orange lens, which the upside of this is even when the lights are off, you can still see this pretty well in the daylight. Now they do make clear lenses as well, and really no huge difference.
It's going to be kind of your personal preference as far as what you think looks a little bit better, but at the end of the day, a really reliable led light that's going to last a long time and a lot of other people see us.As far as the installation goes, it's really easy. There's only two wires to hook up. So it shouldn't take you hardly any time at all. So once you get the light in your hands right away, you can tell that it's going to be well-built. The housing is really thick and solid plastic.
So we shouldn't have to worry about getting brittle and breaking over time. Flip it around to the back inside there's going to be some sealer. So this is going to be submersible. So I do recommend though, if you do plan on putting this completely under water, not a bad idea to turn the power off to the light, just to be on the safe side. We're going to have quite a bit of wire to work with here, about seven and a half inches.So we shouldn't have any issues getting it hooked up. And we're also going to have a sheaving that covers pretty much the whole length of the wires. So little bit of extra protection there, as far as that goes. It does come included with the rubber grommet. So that's nice and I am not saying you have to not worry about picking up separately or you don't have to deal with reusing the old beat up one, so nice little extra you get there.To begin our install, we're going to be here at the corner of our trailer. And the first thing we're going to need to do is install our rubber grommet. So pretty straight forward here, we'll just take the grommet and work it into that opening there.From there, we can grab our light. We're going to run the wires through, push it down into that grommet to get it seated like so, and then we can hook up the wires coming from our light to our existing trailer wiring. So what I'm going to use to do that is these heat shrink butt connectors. These don't come included, but you can find them here at etrailer. Slide the butt connector onto the end of the wire. Cut it down. Going to do that for both of them. So the white wire coming from our trailer light is going to be the ground wire. So I'm going to hook that up to our existing trailer ground and the black wire coming from our trailer light. That's going to get hooked up to power. So here's our existing power wire, slide that in. Perfect down and since these are heat shrinks and I'm going to do is take my heat gun and shrink down the ends.So now it's a good idea to test our light, to make sure it works properly. So we'll put power to it as you can see it illuminates up. So this is what it looks like now that I secured our wiring and I just used a zip tie to get that done. And if you need some of those, you can pick them up right here at etrailer and that'll finish up our look at and our installation of the Optronics trailer Light led clearance and side marker light..

Great addition to the basic, rear brake lights of a camp trailer.
I added these LED RED to the brake/turn function, within the existing, small holes in the rear bumper--much more apparent when stopping/turning.
These sealed LED lights are very common on larger trucks and trailers now. Easy to install and very robust assembly...priced right!
Perfect fit. Fast shipping
I have finally finished the install of the great products that I’ve purchased from Etrailer. Curt 24K 5th wheel hitch, the lube discs, the front receiver hitch tube, the Factory 7-way connector and 7 -way extension (I have 3 7-way plugs on my truck) and the countless number of LED lights. The service is amazing and the customer service I received was fabulous. I really like these folks as they were vary knowledgeable about what I was after and pointed me in the right direction to accomplish my end goal. Thanks to everyone at Etrailer. I couldn’t have done it all without you.
I bought a couple more of these two-diode LED clearance lights to add some more lighting to the rear of my kayak trailer. They work nice and are easy to install in 3/4" holes that I drilled through a piece of aluminum angle. The trailer has orange clearance lights on the front sides, red clearance lights on the back sides, the stop/turn/parking lights on the back, three red clearance lights on the back, and a white LED license plate light. It's really lit up and very visible at night from the rear and sides. Thanks to etrailer.com for great products and services!
My wife and I like to kayak, but we don't like to deal with putting our kayaks on roof racks on the top of a car. So I bought a used Load-Rite trailer that was designed to hold one Jet Ski, and added a frame made of slotted angle and 2x6 lumber to hold the kayaks, and a cargo box from Tractor Supply to hold kayak seats, life jackets, towels, sun-protection clothing, and some spare gear (ropes etc), and bought all new LED lighting from etrailer.com. The paddles are too long for the cargo box so they have to go in the car! The kayaks are tied down to the trailer with several ropes front and rear, so there is a lot of safety factor in the design....I don't worry about the kayaks coming off the trailer! The entire rig works great....when we return from a kayak trip we just back the trailer in the barn and it's ready to go for our next trip. I put a 5" diameter wheel on the trailer just behind the hitch so I can push it around on flat level surfaces. See the pictures.
The lights are perfect as were the previous ones. I’m always doing projects and these are my go to lights for markers and clearance lights.
These are excellent lights. Very small and compact with a very bright output. I used these as marker lights on the rear of my pickup, and it made a huge difference in visibility. Being only 3/4", you can install these in a variety of locations and for a multitude of applications. I highly recommend these and will be purchasing more for additional lighting needs.
from start to finish was great
Great product
works great. bright and compact.
The light was a great replacement for rodent damage on my trailer.
Purchased to replace one that failed on a two year old trailer. Fits and works well. Does not get submersed and not exposed to road salt.
Works perfectly.
Solid and super simple. These lights are bright enough to be seen during daylight and built tough. As you see from the photos, the lights are used as markers for my boat trailer.
