Older incandescent lights can be dim and burn out often. This 4-5/16" round Optronics LED light solves that with seven bright red LEDs that clearly display brake, tail, and turn signals. At 12.8 volts, it draws just 0.234 amps for stop or turn and only 0.033 amps for the tail light, giving you sharp visibility while keeping your power use minimal. LEDs last longer and hold up better to vibration, so you spend less time replacing bulbs and more time towing confidently.
If your trailer ever sees water, this sealed light can handle it. The polycarbonate lens and housing are sonically sealed to keep moisture out, making it a dependable choice even for boat trailers or wet environments. You won’t have to worry about water getting in and damaging the LEDs—the sealed design keeps everything protected inside.
Whether you want a low-profile look or an easier mount, this light gives you both choices. It installs in a grommet (A45GB – sold separately) that fits into a 4-1/2" diameter hole for a flush finish, or you can use the optional BK45BB bracket (sold separately) if you’d rather not cut into your trailer. Either way, the round male pin connection makes wiring straightforward and reliable.

You can count on this light to meet safety expectations on the road. It’s DOT compliant and built with tough polycarbonate components that resist impacts and wear. The LEDs carry a lifetime warranty, and the housing is backed by a 3-year limited warranty—proof that this light is made to last through the miles ahead.

Hello, neighbors and friends, Steve here with etrailer.com. Today we're looking at a LED trailer tail light with a stop tail turn functions, and it's submersible with seven super diodes in a round shape, and it uses a male three pin connector at the back. So folks, this nice round trailer light serves three functions, stop light, tail light, and the turn signal light. It's been sonically sealed, which is basically they take the plastic, put it together, and use super fast vibrations to sonically seal it together. It's gonna be waterproof because of this, and the lens is submersible. The LEDs are gonna make it a great replacement versus changing out the incandescent lights, which we all know over bumps in time just tend to go out faster.
The LEDs are gonna last significantly longer and they're just a great replacement. It's gonna be more efficient. They provide a brighter light with less power output and it is a polycarbonate lens. And the housing now, you can purchase and I recommend you get one if you don't already have one. A recess mount with a rubber grommet that's required to install this.
It does fit into a 4 1/2 inch diameter hole, and as I said, it is a male pin connection and it's been DOT compliant. Now I'm gonna go ahead and light this up for us real quick. You got the taillight function. And then the brakes, taillight, brakes, and let's go ahead and shut off the overhead lights and show you with the lights off. So first taillight, our running lights, and then brakes.
So you can see it gets much, much brighter whenever it's the taillight versus the brakes. And I'm gonna zoom out here real quick. And I will show you the taillight and brake functions zoomed out. So taillight and brakes. So you can see it's much brighter, the brake versus the taillights.
Alright, I'm gonna pop the lights back on. So folks, the overall diameter of this guy is 4 5/16 wide. It is 1 3/16 deep. Again, there are seven diodes inside, it draws about 12.8 volts, and the stop slash tail signal light runs at 0.234 amps, while the tail light itself only runs at 0.033 amps. It's got a nice lifetime warranty on the LEDs and a three year limited warranty on the housing. I'm Steven, thanks for watching, have a great day.

Direct replacement with no issues, excellent packaging and fast delivery.
I am in the process of renovating a 1966 Airstream. I wanted to upgrade the tail lights and the clearance lights. I found etrailer.com on a web search. I ordered the round 4" LED, rubber 4" grommet, and Oval LED clearance light. The round stop with grommet adapeted perfectly into the lens on the Airstream. I will feel so much safer now with the added visability. The lights are stellar.
Easy to order online, Items arrived during the expected delivery date. Have always had good luck with Optronics products. Just waiting for the truck to get back to the shop so I can replace the old incandescnt lights with the new LED lights.
Exact match to the old light
I had to replace one burned tail light on my 2005 cargo trailer. I bought two and replace the other one as well. They work perfectly. The size and the 3 pins connction are the same as the original. A little downside is regarding the packaging. I would expect each light wrapped individualy to avoid the rattling in the box. See pics.
They work great and we're fairly easy to install as a replacement for the old style brake lights with bulbs....
Good job easy to order and I will be b ack
I have a Haulmark utility trailer. One tail light was giving me trouble and I tried fixing it but decided to just replace it with these. They are brighter and fit right in to the old grommet. They were a bit loose so I wrapped some e-tape around them and they are staying in place just fine. I also ordered the pigtails and soldered and heat-shrinked the connections - the factory connecting were "scotch-locks", which I hate. After I did this, I looked closely at the old lights and realized that there was a 3 prong plug which I might have been able to use rather than doing new connections and soldering them, but by doing what I did, I now have tight connections and I can easily replace the light if I ever have to (I got rid of the scotch locks). Yes, I could maybe have soldered the old connections and used the old plug, but it was constructed in such a way that I didn't realize it was there (I thought it was part of the light body). My picture shows the old light and the old plug disconnected from it and the new LED in place on my trailer. It works great - glad I did this. It's much brighter than the old light.
THESE ARE AWESUM. They even look good when off !! Cant wait to BLIND some tailgaters. Drivers who tailgate boat trailers need to be tazed. I ADDED a Sequential Turn module to each side making them even better. A 3rd brake light wire controls others so only E-Trailers Optronics blink. SUPER BRIGHT !! These pull no power at all so I run 30 LED units or hundreds of bulbs all around the trailer.
Bought these LED Stop/Tail lights for my new dump trailer. The factory stop/tails are mounted very low, and any car directly behind me blocks my lights from the 2nd or 3rd car behind me. So I mounted these new ones up as high as I could to let people know I am stopping or turning. I also mounted a side marker light so I could see where the trailer was while backing up at night. The factory marker lights are so low I can’t see them in my mirrors because they are blocked by the step on the drivers side and the spare tire on the passenger side. I am a retired 18 wheeler driver of 47 years.
I bought these lights for a boat trailer. They are very bright and we're easy to install. I would recommend to anyone looking for replacement lights
Best in class service…quick delivery and the right price.
SuperFast Shipping
Great service the exact replacement nee ded.
Great product if you have an odd ball trailer light set up like I do that requires a center mount position plug! Fast east purchase and fast shipping, great company to deal with!
This light was almost an exact match for the stock light that came on the camper. I bought 2 and replaced them both, and they seem to be a little bit brighter than the originals, which I am glad with.
This light was exactly like described. I purchase a lot on line and use amazon prime for free shipping. I could not find this light on amazon and was very impressed that etrailer.com had very reasonable shipping prices. Instead of gouging the cost was in line what normal shipping cost would be. The shipping and tracking were spot on and the lights were delivered as promised. A VERY good company to work with.
We are looking for a supplier of trailer parts .. they had what we needed.
We build aprox 60 trailers a year. I am going to take a good look to see what else we can get from them.
Identical size, shape & function to the original taillight on a 2-yo Master Tow dolly. Replacement taillight from the mfg didn’t fit the original taillight bezel. This one is an exact fit.
My experience with Etrailer was excellent again as always. Always appreciate the explanation and videos to confirm correct product and installation before purchase. Delivery is always awesome as well.
I have not hooked it up to power, but I'm sure it will work. THe only disappointment I had was the light I removed had a rubber pad to help seal the screw holes and wire entry to the back of my trailer to keep moisture out. This light does not have that and it is not available from your company.
Exact replacements for my old tail lights.Fit perfectly. They also solved the issue. Tho old tail lights were allowing the blinker current to back track through the clearance lights. One of tail lights had water in it and when it flashed the clearance lights flashed too.
While I've not yet installed these they look like good replacements for the OEM lights. They are the correct style, size and the screw hole placement seems to be correct. My only reason for giving them an average rating is that they don't come with any gaskets. The original lights have a gasket between the back of the light and the wall of the camper. While the light unit itself is sealed the wires come through a hole in the camper wall and without a gasket the possibility of leaks is there. I will likely buy some gasket material from an auto parts store and make my own. No, I don't think the camper sealant will work as well as a rubber gasket.
Nothing but good.Thanks
Perfect. Exactly what I wanted and needed. Fast shipping. Great communication! Thank you.
