Swapping out dim bulbs for something that actually shows up day or night is a big upgrade. This 20-1/2" x 1" Fusion LED tail light bar uses 19 LEDs with durable surface-mount technology that resists shock and vibration. The LEDs last up to 50 times longer than incandescents and draw very little power—only 0.265 amps for stop/turn, 0.24 amps for tail, and 0.3 amps for backup at 12.8 volts. You get a bright, crisp light that makes your trailer stand out without putting extra strain on your wiring or tow vehicle system.
Instead of cutting in multiple lights for different functions, this single bar does it all—stop, tail, turn, and backup. The clear lens holds both red and white LEDs so you get full brake and turn signals along with a strong reverse light in one streamlined package. It mounts directly to the trailer surface (hardware not included), keeping the setup simple and tidy while reducing the number of holes you need to drill or seal.
Water intrusion is a killer for most lights, but this one’s built to stay dry inside. The housing and lens are sonically sealed into one waterproof unit, making it fully submersible. Whether it’s road spray, storms, or a dunk at the boat ramp, the sealed construction keeps water away from the diodes and circuit board so the light keeps working season after season.
At just 1" tall and 3/4" deep, this low-profile strip stays tucked close to the trailer body for a clean look that won’t snag on gear or cargo. The polycarbonate lens and housing handle bumps, vibration, and UV exposure without cracking or fading. It’s DOT and SAE compliant for trailers over 80" wide, so you know it meets visibility standards right out of the box.
The included 4-wire pigtail keeps wiring straightforward: white for ground, yellow for backup light, red for brake light and turn signals, and black for tail light. That simple layout makes it easy to connect everything correctly the first time and get back on the road with reliable lighting that just works.

Product is awesome.
Nice pair of reverse lights when parking the trailer overnight.
Easily replaced my lights on the cargo trailer and they look great.
They work great , We put these lights on everything we build
Purchasing with etrailer.com was easy, quick and the product arrived when estimated. Excellent service. This light bar was exactly what we were looking for.
Installed six light on my toolboxes Two on left and two on right and two in middle So now I have three stop turn and tail light on each side and two in middle The revers light only tied to middle. The side reverse light put on switch for night time light
Good looking light & bright easy wiring.
exact replacement
Works great, was easy to wire up once figuring out the schematic on the truck side of things. Lights are nice and bright, compact as well. Had to order resistors to prevent my truck from doing the classic GM hyperflash. All good since install!

That hyper flashing is always annoying for sure. But, I'm glad that part # DI34ZR fixed that right up for you, Brad!
