This small LED light puts out a bright, clean amber glow while using very little power—only 0.06 amps at 12.8 volts. With three diodes inside, it delivers dependable visibility without the heat or energy draw of old incandescent bulbs. There are no filaments to break and no bulbs to replace, just consistent light that lasts up to 50 times longer than traditional designs.
Moisture won’t stand a chance here. The polycarbonate housing and smoke amber lens are sonically sealed together to form one piece, keeping water out even when the light is fully submerged. It’s ideal for wet conditions or trailers that see the ramp often, and it stays reliable run after run.
Visibility matters most when you’re on the road at night. The PC-rated beam spreads 90 degrees to either side of center for a full 180 degrees of coverage. Mounted correctly, this single unit works both as a clearance light and a side marker light so others can see you from the front or from either side.
At just 2-1/2" long, 1-1/8" tall, and 5/8" deep, this rectangular light fits neatly on tight surfaces without sticking out. It mounts horizontally or vertically on the trailer surface with two holes spaced 1-3/4" center to center. The simple 2-wire pigtail—one power lead and one ground—makes wiring quick and straightforward.
The rugged polycarbonate construction resists cracks, chips, and vibration damage, keeping the lens clear and the body solid through years of use. And because the LEDs themselves are backed by a lifetime warranty, you can count on this little light to keep shining every time you hit the road.

Hello neighbors, it's Brad here from etrailer, and today I'm at N.A.T.M. And this convention brings a lot of the vendors that we have at etrailer to a convention where we have their booths and their products set up. I had a chance to catch up with quite a few of them. So let's take a look at their products a little bit up close and ask some of the questions to those vendors about their products. I'm here with Erica from Optronics, and today we're gonna be looking at some of the lights that they offer and kind of the breakdown of what each of them do. So what's the first one that we have The first one is gonna be our glow light option.
This is our patented line. You can see the distinction with the smooth lighting all the way across on the light bar, as well as in the four inch round and the six inch oval. These offerings come in grommet and flange mount. We even have a midship option. When you see these, people easily identify these as Optronics.
Most LED lights have hotspots or areas brighter than the rest of the light. Glow lights diffuse the light, giving them a much smoother, more appealing look. So the Fusion, what does that mean So the FusionX is one of our newer lines, and what that does is it offers a couple of distinct looks. You can see we've incorporated our backup option into each look. Here we have it in the standard straight line, and down here it's the same line, only in more of an X or a dog bone, as a lot of people are referring to it in the market.
Similar to our glow light, these are gonna come in grommet as well as flange mount options. One of the biggest, biggest selling points for this for us is it has incorporated backup lighting, and some of them even come with a strobe option as well. So lots of different options, multifunctional, and to the same footprint as a four inch round or a six inch oval. Fusion lights combine stop, turn, tail, and back-up light functions all into one model. Now, when it comes to trailer lighting, obviously you want good output.
So you know, people can know what you're intending to do and you're safe, but also you kind of want your trailer to look cool. So if you're upgrading lights, you guys offer a pretty cool solution. Yeah, so everything that we offer is DOT compliant, including our smoke lens line. And to your point, if you're going for pop, you want that blackout feature. This is a very easy way to upgrade your lighting at a relatively low price point, so. And we offer these, and what you're gonna see here is a lot of our thin line and ID bars, we offer them in many other variations that you're not seeing here. But this is our standard six inch oval. Those are flange mounts. We also offer them in our 3/4 inch markers, our two inch marker lights. This is where all the craze is right now. Everybody wants to black out the trailer somehow. So this is again, a relatively low price point to make a big splash in the market. Optronics lights use a surface mount design where the LEDs are mounted directly to the circuit board. This means less failure points, it's a wider viewing angle With more illumination and a more compact design. Optronic lenses are sonically welded to the housing making for an impermeable seal. This, along with surface mounted LEDs, means that lights can be completely submerged underwater and still function properly. If you have a brand new trailer out there and you have shoddy lights on it, it really does take away from the look of the trailer as well as the safety of being out on the road, and to be able to get replacements that are gonna, you know, update your trailer, it's gonna look nicer. But also LED, more efficient, it's gonna not have filaments to rattle loose. A great option is getting some Optronics lights, especially if you want a custom look to it. It's really hard to beat, and it's definitely something that makes the trailer stand out. But again, at the end of the day, having the right lights means that you're gonna stay safe. So big thanks to Erica for taking the time to break down the Optronic line of lights that they offer and giving us a little bit more understanding.
Ratings & Reviews
Bought the Optronics Sealed Trailer Light, UL95CB, as a replacement for my boat trailer's backup light and paired it with a Optronics Mounting Bracket, A91BB. The combo was a perfect replacement and fit. Installation was easy with stainless steel rivets. Etrailer.com had the best price BY FAR and the products were received prior to the estimated delivery date.
I have had earlier model , with stainless housing,, this new one has plastic chromed housing. Cheaper to make. The first one lasted 8 plus years .
Excellent quality
LPL31CB as used in the flameless heat generators we build for Rain for Rent (used in the natural gas industry). Looks good, works fine, lasts a long time!
I would have liked them to be just a little bigger but were what I wanted but will be returning with fenders.
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 ...
exact replacement for my vexus trailer
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.
Exactly what I ordered and expected with fast shipping!
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.
easy to install and works great
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.
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.
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!
Perfect fit replacement. Delivered quickly at a great price. Easy install and safely back on the road.
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.
LED license plate light really lights things up
The replacement lights are exactly the same as original. Other online offerings were similar but would have required modification. Pricing was competitive as well.
Were a perfect match for the clearance lights on my 2015 American Hauler trailer.
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.
lights are bright and shine in a perfect 180 degree pattern
