Features to know about

Brighter, Longer-Lasting, and Efficient: LED Trailer Light

Tired of replacing bulbs that burn out too soon? This rectangular LED trailer light uses 3 diodes that shine brighter while drawing less power—just 0.06 amps at 12.8 volts. The LEDs last up to 50 times longer than old-school incandescent bulbs, so you get dependable light every time you hook up the trailer. Plus, no brittle filaments or bulb swaps to worry about—just solid performance with every trip.

Worrying About Water Damage: Submersible and Sonically Sealed

If your trailer ever sees the water, this light is ready for it. The housing and lens are sonically sealed into one waterproof unit, keeping out moisture that can ruin wiring or corrode contacts. Whether it’s a downpour on the road or full submersion at the ramp, the internal components stay protected so your lights keep working like new.

Improving Safety and Visibility: PC-Rated 180-Degree Coverage

Visibility matters when towing, and this PC-rated light delivers a wide beam spread that covers 90 degrees to each side for a total of 180 degrees. That means it can be seen from both the front and sides when mounted properly, letting it double as a clearance and side marker light. With its red lens over bright white LEDs, it makes your trailer easier to spot day or night.

Simple Mounting for Tight Spaces: Compact Surface-Mount Design

When space is limited or you want a clean install, this surface-mount design makes it easy. The light measures 2-1/2" long by 1-1/8" tall and just 5/8" thick, attaching flat against the surface without cutting holes. The mounting holes are spaced 1-3/4" center to center, and the single-wire setup grounds through the hardware—quick, neat, and straightforward to install.

Built Tough for the Long Haul: Durable Polycarbonate Construction

Road debris and weather can be rough on lights, but this one’s made to last. Both the lens and housing are polycarbonate for impact resistance and long-term durability. Combined with a lifetime warranty on the LEDs, it’s a small light built for years of reliable performance wherever your trailer goes.

Speaker 1: Today, we're taking a look at the Optronics Mini Sealed LED Marker Clearance Light.This light functions as a marker and/or a clearance light for your trailer. It's a nice, small design. Very bright though. It's a really nice design. Sonically sealed, waterproof design when it comes with the housing, so everything is sealed. You don't have to worry about anything failing or not working if you submerse this in water.So, it's got that sonically sealed, submersible, waterproof design and it's a surface mount installation.

So, you've got a mount hole right here and a mount hole right here. Mounting hardware not included but it can be mounted horizontally or vertically and it is an LED system.LEDs make great replacements for incandescent lights. They last longer, they burn brighter, they're much more efficient. With LEDs, you don't have to worry about replacing bulbs and you don't have to worry about brittle filaments.This does feature a single wire design, for power and then it grounds through the mounting hardware. Again, mounting hardware not included.We have a nice, durable, red polycarbonate lens.

It is PC and P2 rated and it's SAE and Department of Transportation compliant.Now, I took a measurement from edge to edge going this direction and got a measurement of two and a half inches. Side to side going this direction is 1 1/16". Overall thickness is 5/8".We're going to go ahead and hook it up to power. That way, you can see what it looks like with power running to it and then we'll also turn off our overhead lights, so you can see it in a lower light setting.So, you can see here that the unit sends out a really nice, consistent signal. Plenty of light output.

We do have a multi-diode design, so that means that we have more than one LED on the unit. So, the multi-diode design really helps optimize the overall light output.Power draw at 12.8v, is 0.06 amps and Optronics puts a lifetime warranty on the LEDs.And that's going to do it for today's look at the Mini Sealed LED Marker Clearance Light.

The right part delivers on time

Perfect ... This clearance light was for a vintage Holsclaw motorcycle trailer ... can’t get any better than this ...
Replaced the old style with new style ...



by:

exact replacement for my vexus trailer



by:

These guys are good,we build a few trailers in our shop, & these guys have the inventory, you get it fast & you can get them on the phone, we need more outfits like this to do business with! Thanks Guy's--

The product has apparently changes. The part number is the same as what I purchased in the past but these are NOT the same marker light, they are cheap knock-offs. Not even close to the same light. See attached picture, the one on the left is what this part number used to be, the one on the right is the cheap replacement that was sent. Will be returning. It’s too bad I can no longer get the same quality light to match the others on my trailer.



by:

easy to install and works great



by:

So far these led flush mount lights are working great. They're bright and a refreshing update over old incondesant lights. I got these to put on an older camper I purshased. From the photos you can see what was on the camper and I what I upgraded to. The old lights were dull and could barely tell they were lit. These lights bring a modern day update to an 1989 camper. Besides the product being good the shipping was fast and free. And I also like that on etrailers site when your package is in shipment they have a map of the US showing where your package is.



by:

This side marker light is a replacement to an existing one. It is an exact replacement. The new light is spot on to the one I installed about 4 years ago. Good quality. It see’s salt water continuously.



by:

Very strong led light. And very multi purpose. Built a toy hauling trailer for a friend that need some extra light for loading up after dark, and liked to be able to keep a eye on his load after dark. These worked out great, also used some to light up some quads. Very bright for as small as they are. Oh and there are 26 lights on the trailer. Lol no problems with any of them.

Perfect Replacement for marker lights on my 2016 Backtrack trialer for my Xpress boat.



by:

A couple of years ago, I converted a single jet-ski trailer to a kayak trailer to hold my two kayaks, and installed new LED stop/turn/brake lights and clearance lights from etrailer.com. The lights worked great, and I used the trailer for a couple of years before I realized that I was missing a light for the license plate! I'm surprised I never got pulled over by the police! etrailer.com came to my rescue again with this great LPL31CB license plate light. It's very bright and really lights up the plate and the ground around the back of my trailer. Recently I added three more small red clearance lights at the back of my trailer, so the tailgaters and crazy drivers have no excuse about seeing my trailer! See the pictures! etrailer.com has great products, great service, and fast shipping!



by:

Perfect fit replacement. Delivered quickly at a great price. Easy install and safely back on the road.



by:

I purchased this light to replace a cargo trailer light. It isn't a exact match but pretty close. It gets the job done and unless you know the light is different no one will know. Light looks the same as the original.



by:

LED license plate light really lights things up



by:

The replacement lights are exactly the same as original. Other online offerings were similar but would have required modification. Pricing was competitive as well.



by:

Were a perfect match for the clearance lights on my 2015 American Hauler trailer.



by:

So far this license plate light has worked flawlessly! The only reason I didn't give it 5 stars was that I thought the original light (same or very similar light) would last "forever" considering how much we use the trailer. In any case, this light thoroughly illuminates the license plate, so it's easy to see for the toll cameras in our area! I really appreciate the support and products that etrailer supplies. The other lights on my trailer (tail, turn, brake, clearance) have worked great, as long as I maintain a good ground connection on the wiring! I recently had a problem with intermittent lights (blinking on and off), that I eventually traced to a bad ground wire INSIDE the trailer-side wiring connection. I replaced the trailer-side connection, re-spliced the other wires, and wired everything through a weatherproof junction box that I bolted (drilled and tapped) to the side of the trailer tongue. The new ground wire is fastened securely to one of the threaded/bolted connections and seems to be working well so far. I used wired nuts to connect the other wires inside the weatherproof box, so it will be easy to replace connectors if they fail in the future.

I only received 9 of the 10 lights I ordered but after a quick call they are sending my missing light. Thank you!



by:

Exceptional product! Shipping was prompt and the product was packaged with care. Thanks!



by:

Bought as a extra module for my 3 light cluster on the back of my trailer. Being I seem to break lights on accident. It does work.



by:

Exactly what I ordered and expected with fast shipping!
