This 7-1/2" x 3-1/4" oval light uses 16 LEDs to deliver bright stop, tail, turn, and backup illumination without drawing much power. At 12.8V, the stop and turn functions draw only 0.265 amps, the tail light 0.24 amps, and the backup 0.3 amps. The LEDs are more efficient than old bulbs, run cooler, and last up to 50 times longer—so you can count on steady visibility with no filaments to fail or bulbs to replace.
Water intrusion is one of the biggest causes of trailer light failure, but this unit’s housing and lens are sonically sealed into a single waterproof piece. It’s built to handle submersion without fogging or shorting out the diodes or circuit board. Whether it’s road spray or full immersion at the ramp, the light stays sealed tight and ready for anything.
Wiring doesn’t have to be complicated. This light accepts an industry-standard 2-prong PL-3 plug (sold separately) that connects directly for power and ground while sealing off the unused third point from dirt and moisture. The 8" wire lead gives you a little extra room to work with so setup stays neat and quick.
With its built-in black flange, this light mounts right on the surface of your trailer—no need to cut large holes or modify panels. Just line it up, secure it with mounting hardware (not included), plug it in, and go. The low 3/4" profile keeps it close to the body for a clean, finished look that won’t snag or catch.
The LED circuit board uses surface-mount technology for better shock resistance and improved heat distribution. That means fewer failures from vibration and a thinner, tougher design overall. The polycarbonate lens and housing add another layer of strength, keeping everything protected while staying DOT compliant under FMVSS 108 and CMVSS 108 standards.

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.

Exact replacement to original that came with our cube truck. Ordering was easy and shipping was lightning quick. Thank you very much!
These lights are great on my PU camper , a little over priced - probably as they are waterproof. Very bright back up and break/ turn lights . Running is more subdued, so as not to be mistaken for breaking
Awesome service.
After over a year, and 30k miles on a jeep that is well used, heavily wheeled and abused, I haven't had one single issue, great service and fast shipping by etrailer.com... 10/10 would recommend
Perfect replacement. As advertised!
Easy to swap out for the one on my Lance truck camper which had lost its seal.
Used these on my 1985 custom pickup truck flatbed conversion, they look good and are very bright. Only complaint is that the wires come out of the unit in a "straight line " so you either have to "mill" a slot in the mounting panel or drill a large hole.
Please see attached photos of my lights installed on a trailer.
These lights are a direct replacement for the stock optronics stop/turn/tail lights on my Sundowner horse trailer. It was pre wired from the factory for backup lights but none were installed. If you pull off the rear right side light cover of the trailer there is a yellow wire that is capped off. Double Check with a light tester that it is the power wire for reverse lights. I drilled out the old rivets and installed the new lights with the reverse light wired up to the yellow power wire
The leds are nice and bright for all functions
I like the looks of them! I hope they last!
The original led tail lights have been replaced twice in 6 years. That’s unexceptable!
Working on a project truck needing a low profile taillights. Come across ETRAILER.COM and found just what I needed. Ordering online was easy and was very impressed on how fast I received them. Installation was made easy. 4 screws along the edge of the one piece sealed unit. 4 wire pigtail made wiring easy. Adding the finished trim to cover the screws gave it the look it needed. I would recommend this product and ETRAILER to anyone who is looking for stylish lights with ease of installation. Thanks ETRAILER.
I just got a new boat and had damaged the trailer light no other place around had a matched light even the large outdoor shop (starts with a C) sold me the incorrect ones for $60. Then as frustration started impacting me. I saw etrailers online, saw a light that was identical, took a chance and it was the exact light for only 1/3 of the price I paid at the large outdoor store. End result, I'm very pleased with my purchase, shipping and overall.
I chose the STL211RCB when I recently rebuilt a small trailer I use for my business. I wanted a fixture with a bright reverse light, while also taking up the least amount of space possible. This fixture exceeded my expectations, and has performed flawlessly since the day I installed them. The previous incandescent fixtures were always needing repair to keep them working. They were mounted low, and hard to see in the daytime. The small footprint of this fixture allowed me to relocate the taillight to a better position, allowing for better visibility, day or night. I would recommend these to anyone that needs to back up a trailer in the dark a lot.
5 th. set of lights our Fire Department have purchased, we are very happy with them.
Easy to wire up and to mount, They are very bright and the surface is a Big Plus.
Would recommend these lights to everyone out.
These lights are great. The backup lights work awesome! No more dragging the brake while backing up just to be able to see when I'm backing up.
On a 7 pin round trailer plug connect to the "reverse lights" not the center auxiliary power pin. Connect both of the pigtail grounds up to make them work.
I ordered the STL101RB Trailer Tail Light - Stop, Tail, Turn, Backup - LED to replace the standard tail lights on my Yamah Drive G19 golf cart. They replaced to stock ones perfectly as a neat way to add a backup lights for a custom feature. The backups led are actuated by the reverse switch on the dash.
It should be noted that the ground terminal on the two wire pigtail connection is not wired internally to the backup LEDs. They rely on the ground supplied by the three wire pigtail. Not a big deal, but worth noting. It throws a curve when bench testing.
These lamps add a nice custom touch!
I've bought a trailer hitch and brake,turn signal,taillight and backup light combination flush mount from u guys the trailer hitch mounted perfectly on my ford pickup i put a wooden bed on my pickup and needed some lights for it so i got these lights and super happy with the way they look on my wooden bed installed easily they are nice and bright would recommend your products to other people
WOW!
I recently ordered lights to replace the original lights on my neighbor’s 20 year old DewEze Jay Bed and I couldn’t be happier with the entire process!
Everything arrived quickly and in perfect shape with plenty of cushioning to prevent damage.
The combination tail lights are simply perfect for the application and the reverse lights are BRIGHT!
I actually prefer these surface mounted tail lights over the gasketed style that is currently on my flatbed trailer.
In the future I will be ordering several sets of these to replace the lights on the trailer and for a flatbed that will be going on my own truck, I’m planning on using two sets in the truck’s flatbed with one set on the headache rack using the reverse lights as bed lights, I shouldn’t have any problems seeing stuff on the bed at night.
I bought this set to install on the back of my enclosed overland trailer.
On occasion, i carry a basket in the trailer hitch location and my stock lights get covered. The Fusion LED lights were easy to install, very durable and are super bright. At night you can see them from a great distance!
Unlike the cheap Amazon LED lights, this one is actually submersible and water tight. Just mount and connect.
This is the third boat trailer that I have used these lights on. While the backup lights aren't "daylight" bright they do a pretty good job. (it's my understanding that "back up lights" are regulated as to total light output) If you need more light you could always use a seperate "work light" in addition to your regular stop/turn/tail light assembly. One of the nice things about these lights is that they fit in the standard oval mounting hole as a regular oval tail light assembly. Another is that the "white" LED's turn "red" when the stop or turn function is activated.
I like the fact that I can have (at least a fair amount) of light to aid in backing the trailer at night down those pesky dark boat ramps. They also come in handy to alert others that you are backing up.
As a technical note: the back up light gets it's ground from inside the tail light NOT from the white (ground) wire from the back up light pigtail. I other words, if you apply power to the red wire and ground the white wire.......the backup light WILL NOT ILLUMINATE! That does not mean you have received a bad light from Etrailer. The white wire on the back up light pigtail (2 pin,....1 red and 1 white) IS NOT USED. You must use the white wire from the stop/turn/tail light pigtail (3 pin,...1 red, 1 white, and 1 black) as your ground for the back up light to work. The earlier version of this light had the grounds separated.
Awesome lights, nice and bright. Being able to add reverse lights to my boat trailer is very helpful on dark boat ramps. The Combo light that fits in my existing grommet was nice since there was no room to add an additional light.
I built an off road high clearance rear bumper with tire carrier swing out for my Tacoma. The lights were added to the rear bumper for added safety. The reverse lights work well, and add much needed additional lighting while reversing. I am pleased with the lights, they are high quality, and the lenses are still clear after being exposed to the elements for about a year. I have no problem recommending them or etrailer to anyone.
Good replacement for an existing light on our travel trailer. Trailer was wired for backup lights but none installed. This unit will give me tail, turn, brake and backup lights.
Measurements for mounting holes was exact. Did not have to drill other holes. This is a surface mount. I did have to modify the reflective trim ring that was on my original light for it to fit the new light. The housing on this light was slightly larger but the overall dimensions were the same.
Some grinding on the trim with the drimmel tool solved the problem.
Would be good for initial installation also. Initial installation would require a hole near the center of mount location to allow wiring to pass through trailer. Seems to be a quality product.
Attached photos of lights installed.
These are bright LED lights, and having the LED back-up light in the center makes hookup very easy. The only problem I had was mounting the STL201RB light in the A45GB rubber grommet with the BK45BB mounting bracket. I tried following the etrailer videos with no success--in fact I was pressing on the light so hard in an attempt to insert it in the rubber grommet and mounting bracket that I was afraid I would break the light. So I decided to try a different approach. I mounted the grommet in the bracket (easy part), then immersed that assembly into near boiling water for about 10-15 minutes. This softened the rubber grommet sufficiently such that inserting the LED light into the softened grommet was now very easy. I used heavy gloves while assembling it, and rubbed a bar of hand soap around the inside mounting surface of the grommet just before inserting the LED light. Really worked well---just need to take caution when handling the very hot bracket and grommet assembly right out of the hot water bath. The attached picture shows one of the LED light assemblies, with associated wiring, just prior to checking out the electrical hookups to make sure the wiring was done correctly. The other picture shows the round LED light along with a small red LED side marker light after installation.
Everything they said they were, Internet assistance and colors to match you vehicle make and model and look great
