Features to know about

Brighter, Longer-Lasting Illumination: 12-Diode LED Power

Old bulbs can fade fast or draw too much power, but this Optronics LED trailer light is built to shine bright and stay efficient. Its 12 diodes deliver strong, even light for stop, tail, turn, and backup functions. At just 12V and low amp draws—0.01A for tail, 0.09A for stop, and 0.26A for backup—it puts out impressive light while keeping power demands down. LEDs last far longer than incandescent bulbs, so you’ll spend more time on the road and less time swapping parts.

No More Water Damage: Fully Sealed and Submersible Design

When road spray or boat ramps come into play, water shouldn’t be a worry. This light’s housing and lens are sonically sealed into one waterproof unit, making it fully submersible. That sealed design keeps out moisture and dirt so the internal electronics stay protected trip after trip. Even in wet or harsh environments, the light stays clear and reliable.

Simple Setup and Secure Mounting: Integrated Flange with 4-Wire Pigtail

Installing new lights doesn’t have to be complicated. The built-in black flange lets you surface-mount the light directly without any special brackets. A 4-wire pigtail with 0.180" male bullet connectors makes wiring straightforward—no cutting or splicing needed for connection. It’s a clean fit that saves time while giving a solid mount that stays put on rough roads.

Slim Profile That Fits Tight Spaces: Compact Oval Build

Some trailers don’t leave much room for lighting, and that’s where this compact design works best. Measuring just 7-1/2" long x 3-5/16" tall x 3/4" deep, it keeps a low profile without sacrificing brightness or visibility. The durable polycarbonate lens and housing add strength without adding weight—just 0.275 lbs total—so it’s tough but sleek.

Reliable Compliance and Peace of Mind: DOT Approved with Lifetime LED Warranty

You want lights that meet safety standards and stand the test of time. This Optronics LED trailer light is DOT compliant for legal road use and comes backed by a lifetime LED warranty. That means dependable performance you can count on every time you hook up your trailer.

Video Transcript for Review of Optronics Trailer Lights - Tail Lights 4 Function - OPT46KB

Hello, neighbor, Steve here with etrailer.com. Let's take a look at our Optronics LED Hardwired Trailer Light stop, tail, and turn, even back up. So, it's got four functions, light, stop, tail, turn, back up, and the oval red clear lens that comes with it. It's gonna have 12 diodes and it is a four-function light and it is sonically-sealed and its waterproof housing and polycarbonate lens makes it submersible and durable. The LED lights are highly efficient, durable, and long-lasting and super bright. Now, this mounts on the surface of the trailer with the built-in back black flange here.

Hardware sold separately, there'll be four screws. And it is a four pigtail, what we call a bullet-style connector, and it is DOT-compliant. Overall dimensions, 7 1/2 overall, 3 5/16, and 3/4 of an inch deep. Now let's go ahead and put some power to it, and we'll go through all the functions real quick. So, that would be your running lights.

It's not too bright. Back up, and brakes. And then obviously, if you do your brakes and running lights at the same time, you would have both of 'em. So, I'm gonna go ahead and shut off the overhead lights and let's go through those again. Just your running lights, back up and brakes, and then again, back up and brakes at the same time, and individually again.

So, very nice, very bright. Let's go ahead and zoom out and let's look at them. Now, these are pointing up so they're not pointing directly at the camera, but that gives you an idea of about how bright they are. Let's see if I can turn it here for you. Okay, and that's gonna go through all the sequences here with this particular light, and that's also gonna wrap it up for us, folks.

So, lemme turn my lights back on here. Thank you so much for joining me. I hope this walkthrough with you today has been helpful. Again, nice LED, long-lasting and waterproof in this case. I'm Steven, thanks for watching and have a great day.

These lights were perfect for the application I intended them for them! I've been getting a dune buggy ready for road-legal operation, and with these things, my motto has always been "less is best" for styling and function - therefore I needed a compact rear light that had all the bells and whistles (tail, turn, stop, & back-up lights). The LEDs are plenty bright for the job. If doing this sort of project with this style light, I recommend ALSO using the Roadmaster Brite-Lite 3-to-2 taillight converter (part# RM-732), sold by etrailer, to aid in making this compact taillight work as one unit. Great product!
