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.

Evidently just fine. I traded my camper in on a new one and it was just fine during the inspection.

Pratiquement tous les feux arrière à DEL enfichables Optronics ont la prise décalée sur un côté. Quel était le numéro de pièce du feu que vous remplaciez? Pretty much all of the Optronics plug-in LED tail lights have the plug offset to one side. What was the part number of the light you were replacing?
