This LED trailer tail light uses 14 bright diodes that deliver sharp, clean light with less power draw. At 12.8V, it only uses 0.259 amps for the stop function and 0.062 amps for the side marker, making it far more efficient than incandescent bulbs. With no fragile filaments to burn out and a lifetime warranty on the LEDs, you’ll get dependable brightness every time you hit the road.

Water and moisture can destroy a trailer light fast, but this one is built to handle it. The sealed, waterproof housing is completely submersible, so it stays protected even when launching boats or driving through rain. The molded plastic body and durable acrylic lens keep out dirt and water while standing up to years of vibration and shock.
No need for extra parts or add-ons. This single light handles seven functions—stop, turn, tail, rear reflex marker, side marker, side reflex reflector, and license plate illumination. The built-in reflex reflector means you don’t have to install a separate one, keeping your setup simple while staying fully visible from all angles.
Installation is straightforward thanks to the stud mount spaced on 2" centers and a 2-wire pigtail with 15" leads. The self-grounding design means it grounds through the mounting hardware itself—no extra grounding wire needed. That makes wiring cleaner and helps ensure a solid connection every time.
The LED circuit board uses surface-mount technology (SMT), which improves heat distribution and resists shock and vibration better than traditional setups. That solid construction helps keep your lights running smoothly in rough conditions while maintaining consistent performance over time.

Randy: Hey guys, Randy here at etrailer.com. Today we're going to be taking a look at the Optronics led trailer light. Now these are available in driver and passenger. The driver's side has our license plate light here on the bottom to illuminate that. The passenger side is not going to have that clear panel on the bottom. We use 14 LEDs over here on the driver, and you're going to have 11 on the passenger.
Now I really like these lights. They have a very durable housing, not a whole lot of give to it. The acrylic lens both here and on the side, really quite durable. Other than like backing into something, I really don't think you'll have to worry about these too much. Something I do also like about these, they serve more than just the lighting functions.
These are going to have built in reflectors here that go around.Of course, we're going to have our tail lights, going to have our turn signals. We're going to have our brakes, but also when our trailer's not in use or when it's parked, those reflectors are going to stand out. Same here on our light on the side, got the reflectorized lens there. So not going to need any additional reflectors on our trailer. Now this is a two wire design light.
So we just need to connect it to a good ground through our mounting studs, then our running light signal, and our turn and brake signal. It's going to give us all of those as we head down the road. I think it's going to be a really good addition to just about any type trailer under 80 inches. It is a submersible light. So even in marine applications and things like that, I think it's going to work out really well.You do want to unplug your lights.
I always recommend unplugging your lights. Some people do, some people don't, but I just don't like water getting in there when we're making electrical connections. The LEDs though, they are going to burn a lot brighter. They burn a lot cooler. They don't use near as much energy as what an incandescent bulb does, and they tend to last a lot longer. So more and more when working with customers, I typically see them going with LED lights when they're replacing lights on their trailer. If you had some incandescent lights up front, you don't really want to mix and match, that's up to you, but I would certainly recommend upgrading. You're going to do a lot less of chasing those bulbs or chasing the wiring to figure out what's gone wrong. Generally, it's going to be in that bulb socket.You got some kind of corrosion there. I think they're going to be a really good addition. Our customers, when working with them, they seem to be really pleased with them. They like the way they work. They like the way they look. I do too. I think by adding these to your trailer, you can solve a lot of the issues that we used to have with those incandescent bulbs and still keep it looking pretty traditional.To begin our installation of course, you'll need your old light removed from the trailer. The first thing we like to do, this light grounds through your mounting bracket. So it's a good idea to take a wire brush and really clean both surfaces of this off to make sure you don't have any scaly rust or anything like that. That can cause you issues down the road. You'll notice there's this little gap here, right where the wiring comes out. You want your wiring to be stored down and in there as we slide it into our bracket here. We're just going to take the provided hardware. Got a flat washer and flange nut there. We'll use our seven sixteenths. It's going to get that snugged down. No need to over-tighten these, but you do want them to be good and snug.We are looking at a two wire design that comes off of our light. This is my preferred style. Some of them will have three wires, which is a ground wire that comes off. I like grounding them right through the attachment points. We'll strip those back where we want them and I like to twist it up really well. You notice we're using heat shrink butt connectors here. I definitely think this is the way to go. This is going to ensure that you're going to have a good corrosion resistant connection here because moisture can't get in. Then we just need to connect it to the running light signal for our brown wire coming back from our trailer connector upfront. Generally, that's going to be the brown or darker wire, place that in and get it crimped down.Then for our yellow wire, which is going to be our turn and brake signal, it'll just need to go to the other. We'll use a heat source to get that shrink down. Here of course we're using a heat gun. Now with those connections made, I just like to tidy it up here. I like leaving excess, especially when we have something like this where we can get it tucked up and zip tie it off. In some cases you might want to trim it a little bit shorter, but remember if you ever have a problem with your wiring, you'll need to get it from somewhere. So if you didn't store any extra upfront, make sure you have some back here.Now that takes care of the driver's side here. That's the one that has that clear lens we talked about. Now you'll just head over to the passenger side and just repeat that same process. Only you're going to do green to green rather than yellow to yellow. All right, now we'll just test them out and make sure everything's working properly. We're going to use our trailer tester here, but you could just as easily plug it into your towing vehicle. You would start by turning on the running lights, make sure they both come on. Then we can check our left turn signal, check our right turn signal, and also our brakes. It looks like everything's working properly. All in all guys, I really like this light. I think it's going to be very durable and very sturdy. I think it's going to last for an extremely long time, especially if you're used to incandescent lights. These LEDs are really the way to go. All in all, this is definitely what I would put on my trailer and definitely one I would own.
Ratings & Reviews
I ordered this as a replacement for an older trailer light that I had damaged. It is so much better than the old one, I had to order one for the driver's side as well! The LED lights are much brighter than the older, conventional bulb lights I had. Also, the side light does not extend out as far and will be completely protected by the light frame. I had rubbed the old light against a post and torn off the side light. This is a much better design!
Installed the new lights today. Easy peasy. I grew up on a farm, in the country, and have been fixin' and futchin' with trailer lights since I was 6, it seems (I'm 74 now). Hopefully this is the last time I'll need to fix the lights on this particular trailer.
Unlike my previous lights, these are really waterproof and work great. Funny thing- someone just backed into my trailer and took out my passenger side light last weekend so I'm ordering a new one as I type this.
