  • Simple Mounting: Surface-mount design with 3" hole spacing fits standard setups.
  • Road Legal Assurance: DOT compliant for safe, compliant trailer lighting.

Features to know about

Brighter and More Efficient Lighting: 4" Red LED Design

Older incandescent lights tend to fade or burn out over time. This 4" x 2" rectangular LED trailer light solves that with three durable diodes under a red lens that stay bright while drawing only 0.06 amps at 12.8V. It’s energy-efficient, long-lasting, and keeps your trailer clearly visible without putting a strain on your wiring system.

Multi-Purpose Functionality: Clearance, Turn, or Side Marker Light

Instead of buying separate lights for different uses, this one handles several jobs at once. It works as a clearance light, turn signal, or side marker—making it simple to get the coverage you need. The P2 rating means it’s equally visible from the front and side, adding extra safety and visibility every time you’re on the road.

Built-In Safety: Reflex Reflector for Added Visibility

Even when the LEDs are off, the built-in reflex reflector keeps your trailer visible to other drivers. It reflects light from headlights or street lamps back toward the source, helping mark your trailer’s position in low-light conditions. That extra passive safety feature means you’re covered day or night, powered or not.

Simple Surface Mount Setup: Straightforward Installation

Mounting is quick and clean thanks to the surface-mount design and black ABS plastic base. With mounting holes spaced 3" apart (center on center), it attaches easily where your old light was installed. The snap-on acrylic lens makes future replacements simple, and the 3-wire pigtail—power, turn, and ground—hardwires directly into a standard 12V DC system for a solid connection that lasts.

Video Transcript for Review of Optronics Trailer Lights - Clearance Lights - OPT44NR

Hello, everybody. This is Jeff at etrailer.com. Today I'm gonna take a look at this Optronics LED Trailer Clearance Turn Signal or Side Marker Light with the Reflex Reflector in the Red Lens. Now, this is a rectangular LED trailer light that'll function as a side marker light, a clearance light, or a turn signal light. You can see, it is a red lens over three wide LEDs, and it does use a built-in reflex reflector to remove the need for a separate reflector. Now, I have this hooked up to some 12 volt power, and I do wanna show you the light.

So, what we're gonna do, is go ahead and turn on the 12 volt power. And there's your side marker light or clearance light. And then, we'll go ahead and turn off the overhead lights. And if you do hook it up as a turn signal light, you can see that it'll also offer the turn signal function. Now, they do use LEDs.

They do make great replacements for the incandescent lights, 'cause they'll last 50 times longer. They are more efficient, they provide brighter light with less power output, and of course, no bulbs to replace or (indistinct) to break. And the lifetime warranty on LEDs. Now, this is a durable, I'm gonna go ahead and disconnect it from our power here. The base on it is a durable black ABS plastic base.

The lens is a nice, easy snap-on acrylic lens. Very easy to replace. And again, this is compatible with 12 volt DC electrical systems. It is designed to mount onto the surface of the trailer. Now, the hardware installer is not included.

You can see, it offers a three wire pigtail, with the two power leads in the ground wire. And this light is DOT, Department of Transportation, compliant. It is also P2 rated. Few specs on this. The overall length, we'll get our ruler out here and we'll go to the back, overall length from one end to the other is right at four inches long. Height of it is two inches tall. And the total depth of it, one inch deep. Now, the distance between the mounting holes. These are the two mounting holes here that you mount. Center to center on those is right at three inches. And the power draw on this at 12.8 volts will be 0.06 amps. But that should do it for the review on this Optronics LED Trailer Clearance Turn Signal or Side Marker Light with the Reflex Reflector.

Safety update for my antique Shasta. Bright and well made' my only problem was my own failure to order the stainless steel rings to really finish off the install and add some more strength to the light structure; don't be cheap order the rings.



by:

Restoring my old '71 Shasta camper I wanted to upgrade the analog taillights with LED's. These lenses worked great and I was able to use the old aluminum back covers. These lenses are close to the old ones in shape and size and will make the camper safer on the highway. Thx



by:

Quick and easy!!



by:

I think the photos and the video accurately depicted the light. I don't plan on submerging my lights (I installed them on a car vice a trailer), but I believe the lights would do fine. they are completely enclosed. Great communication from Carol at etrailer following purchase.i posted a video of the installed lights to YouTube



by:

Ordered two so I assume they placed both in one bag and the bag has no serial number on it for reference in the future. One was loose in the shipping box and could have been easily broken with no buffer added to package. Shotty shipping.



by:

Fast delivery!

I am very satisfied with etrailer and the ordering and shipping of the products, I had questions on the description of the round tail lights so I called etrailer and it was cleared up. The lights are perfect for my application. They are mounted on a small camping trailer that is pulled behind a motorcycle and space is limited so these being only 3/4" thick is great and because they are LED it makes it easier on the motorcycle electrical system. The outside diameter is 5 5/8 inch as on the video review along with all the rest of description is correct. A very nice light indeed.



by:

Great , fast service when I needed them



by:

These were really easy to install. I found that I needed more markers on the side of our 5th wheel trailer (44') I actually posted a few videos of people turning into our lane thinking they had passed the trailer. Connected to the rear and front marker lights and I have had no problems since.



by:

Direct replacement for one exactly like it Same brand and all, although the original lost a few LED's It makes me wonder how good these lights really are..



by:

Very bright & well made, I replaced these on my class A RV, the OEM manufacturer used them on the original build in 2014, replaced with a new set in 2020 and couldn't be happier knowing every thing behind me on the road sees me stopping, turning, whatever... Very good - quality product! Highly recommended. To be clear, I purchased these myself at full price from eTrailer!



by:

Shipping was quick and efficient. the selection gave me the ability to find exactly what I needed.

One piece, easy installation. Worked like a charm!



by:

We are really happy with this product and it fit our trailer perfectly. Plus, they were easy to install. All in all, it was a nice update to our 1960s Apache trailer.



by:

Easy ordering of the correct light for my R Pod and amazingly quick delivery!



by:

I have a Newmar coach which I had a LED taillight that burnt out. I called Newmar and checked several other suppliers but no one had the one I needed. I then logged on to etrailer.com, found the exact match, ordered and received it. I’ve used etrailer in the past for towing related items but they will be my first shopping stop for all my RV needs.



by:

Perfect fit and these lights came with rubber gaskets which the factory lights to my surprise did not!



by:

Replaced problematic lights on my vintage trailer. Eliminated bulbs and problems associated with them and replaced with LED. Easy install and quality product



by:

updated our motorhome from the old square type with bulbs to these round type led lights and could not be happier..bright and a more modern look...highly recommended



by:

Awesome business, quick to ship and came as advertised. I keep in my accessories favorite page.



by:

Optionics LED lights with brake and turn. Excellent shipping time and lights are exact replacement. I like that they have a lifetime warranty as I’m already on my 3rd set.
