Features to know about

Brighter, Longer-Lasting, and Efficient: 19-Diode LED Tail Light Bar

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.

Fewer Lights, Cleaner Install: Built-In Backup Function

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.

Ready for Water and Rough Roads: Sonically Sealed, Submersible Housing

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.

Low-Profile Fit That Looks Sharp: Durable Polycarbonate Build

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.

Simple Wiring That Makes Sense: Four-Wire Pigtail Setup

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.

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!

  • Parts Needed To Wire In Additional Tail Lights On A Travel Trailer
    Hey Steve, Personally, I hate the metal junction boxes that manufacturers use so I'd yank all of the wiring out of that one and switch to a junction box like # 3375601101. The separate posts will help you easily organize all your wiring and give you a more secure connection using ring terminals over the wire nuts the manufacturer used. This will also come with rubber plugs to help seal up the box and prevent water from getting in and corroding the wire. I do agree that running some new...

  • Will Entire Fusion LED Combination Tail Light Bar Flash with Turn Signals
    The Optronics Fusion LED Combination Tail Light Bar # STL264RCB that you referenced will not separate out the left and right turn signals so the entire bar is going to flash with either function activated on the trailer. This will be the case with any of the similar trailer light bars that we have available. I have attached a short video review that you can check out as well.
