This 4-1/16" round Optronics LED light gives you brake, tail, and turn signals that shine bright and stay efficient. With 21 diodes behind a red lens, it’s more durable and energy-efficient than incandescent bulbs. It runs on a 12V DC system and comes backed by a lifetime warranty on the LEDs, so you can count on it to perform for the long haul without worrying about burned-out bulbs or weak signals.
Water exposure is no problem for this light. It’s fully waterproof and submersible, which means moisture, rain, or even dunking won’t get inside and damage the LEDs. Whether your trailer gets splashed or spends time in wet environments, this sealed construction keeps everything protected for consistent performance.
Installing this light is straightforward. The black die-cast steel housing mounts on a post for a sturdy pedestal setup, and all the needed hardware is included. The included pigtail hardwires directly to your trailer—white wire for ground (through the mounting hardware), black wire for running lights, and red wire for stop/turn functions—keeping it simple and secure once it’s in place.
The solid black steel housing not only looks clean but also adds strength for long-term use. At 4-1/16" in diameter and 1-3/4" thick with an overall installed height of about 4-1/2", it’s compact yet sturdy. It’s also DOT compliant, so you know it meets safety standards while giving your trailer a modern LED upgrade that holds up to real-world use.

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Optronics LED single face trailer stop, tail and turn light. This is a DOT compliant four and one 16th inch diameter round single face light with the rear facing red lens. This will provide your stop light, your turn, and your taillight signals. It does hard-wire into your 12 volt DC systems. It does have a post mount installation.
The hardware for that is included so you can get this mounted properly. And it does have a durable black die cast steel housing. So this is gonna be great for your farm equipment and agricultural applications where you're gonna need something very durable. The housing and lens unit are sonically sealed so it is gonna be waterproof, can be submerged, so no worries about getting wet. We do have the red lens over the 21 LEDs.
If you're not familiar, LEDs do make a great replacement for incandescent lights, because they are gonna be more efficient. They're gonna provide a brighter light with less power output and the bulbs aren't gonna need to be replaced because they don't have those brittle filaments like your incandescent lights do. So these are gonna last about 50 times longer. This actually comes with a lifetime warranty on the LEDs so you can trust they are gonna hold up really well for you. So a very durable option here.
The LED circuit board also has a durable surface mount technology construction that's going to be designed to withstand shock and vibration and allow for improved heat distribution and a thinner construction. So again, all around a very durable light for you. So especially great for the farm equipment and agricultural applications. Just to give you a few dimensions here you can see this is just over four inches, we'll call it four and one 16th of a inch in diameter. And then our depth, we're looking at about one and three quarters from the very front.
That bubbled lens there to the back of our housing about one and three quarters of an inch deep. The cable that's included here are wires. It's going to be approximately six inches long. So a little bit of wire to work with. Make sure that you can get this hard-wired into your 12 volt DC system. And that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

Good job
Super fast shipping ! High quality product ! Could not be happier ! AAA + The Etrailer team knocks it out of the park ! Thank you very much !
Lights function very well. No instructions enclosed as to what wires go to turn, stop and running lights. Not a big deal, but you will need to look it up on Google. It would be a 5 star with directions.
they sell this with a bad description that makes you think its a pair of lights like every other vendor sells for $[XX] a pair !these are not worth $[XX] each !dont buy them customer service is no help either .
Quality shows. Easy to install. Bright from the rear and side. Really like the looks.
Fast delivery. As advertised.
Delivered exactly what I ordered
Perfect for my odd-ball project. etrailer's customer service helped verify stock and get the product to me in under 24-hours.
These lights are great! Very bright and well made, they give my military overland setup a nice vintage look...much more attractive than the standard round or square trailer options.
