Older bulbs dim over time and draw more power than they should. This low-profile 18" LED tail light solves that with twenty efficient diodes that give off a crisp red glow for brake, tail, and turn signals. The LEDs use less energy than incandescent bulbs but shine brighter and respond faster, which makes your signals easier to see day or night.
Moisture, dirt, and vibration can ruin weak housings, but this light is built to take it. The red lens and housing are made from durable polycarbonate that’s weatherproof and sealed against road grime. It’s designed to hold up through long trips and rough conditions without cracking or fogging up.
When space is tight, this light’s slim 1-1/2" tall by 3/4" thick profile keeps it flush against the surface instead of sticking out where it can snag. The surface-mount design uses two mounting points spaced 15-7/8" apart and installs cleanly using a standard hardwire connection. The included 3-wire pigtail makes setup straightforward—white for ground, red for brake, black for tail.
Whether you prefer a horizontal or vertical layout, this light adapts easily to your setup without extra brackets. It’s DOT and SAE compliant too, so it meets the standards you need for visibility and safety on the road.
Quality construction backed by a 2-year warranty means you can count on consistent performance trip after trip. Once it’s installed, you can focus on the drive instead of worrying about your lights failing when you need them most.

Speaker 1: Today we're taking a look at a red LED trailer tail light. Now, this trailer tail light serves three functions. With this light, you have your stop light or brake light, tail light, which is your running lights, and your turn signal light. It can be mounted horizontally or vertically, whatever works best for your application. It does feature a really nice weatherproof housing and lens unit that's strong and durable. Protects the internal LEDs from dirt and moisture.
This strip contains a total of 20 diodes, or 20 LEDs. Now, LEDs make great replacements for incandescent lights. They last longer, they're known to burn brighter, and they're much more efficient. You don't have to worry about changing bulbs or worry about brittle filaments with an LED systems.When it comes to the wiring, it's a three wire pigtail. Your white wire's your ground wire.
Black wire is for the tail or running lights, and then the red is or stop and turn. It's SAE and department of transportation compliant. It mounts directly on the surface of the trailer. Hardware to do so is not included, but it does have two mount holes, one right here and one right here, and these are separated apart from one another on center by 15 and seven eighths inches. The overall measurements of the unit, measuring edge to edge, it measures about 18 inches long.
Overall height is an inch and a half, and the overall depth is about three quarters of an inch.We're gonna go ahead and hook it up to power so you can see what it looks like with some power running to it. Again, the white wire is our ground wire. Black is for our running lights, and then red is for the stop and turn. So, you can see here it sends out a nice bright, consistent signal. Really nice design with the LEDs directly on top of one another, and then when we apply our brakes, you can see how that signal output increases, and it does that same thing when we activate our turn signals.
Again, this light contains 20 diodes, so the multi diode design really helps optimize the overall light output.That's gonna do it for today's look at the red LED trailer tail light.

Awesome product great quality and fast speedy delivery!
Great service
Screw holes did not line up with the old ones on Thor Windsport 29M, But got it to work, The number of LED's were not the same but will be ok. This was the only place I could find one that looked the same as what I have without going to a dealer.
Looks good
They work great!
Not as bright as OEM and does not fit OEM holes, had to drill new ones, got buy another so it matches other side now
All the LED lights work as OEM. Thank y ou
Very impressed with the quality, the original rv lights were lacking, so we added these to our rv bumper. Big difference!
No issues ..... I added these to the back of our Fleetwood Discovery LXE motorcoach. The are higher up than the factory brake lights and provide extra visibility when pulling our tow vehicle or trailer.
