Optronics TLL9RK LED Trailer Tail Light Kit with 25-Foot Harness and License Plate Bracket

The Optronics TLL9RK is a complete LED trailer tail light kit built to bring a trailer's rear lighting up to a single, matched standard. The kit pairs one STL38RB driver-side tail light, which has 3 additional LEDs built in for license plate illumination, with one STL39RB passenger-side tail light, so both sides of the trailer are covered by a single purchase. Each light uses sealed LED construction with 6 rear-facing diodes plus a side marker diode, giving reliable stop, turn, tail, and side marker function in a waterproof housing. A 25-foot wiring harness and a license plate bracket are included, along with the mounting hardware needed to install both lights, so the kit covers the wiring run from the tow vehicle connector back to the lights as well as the physical mounting. The lens is acrylic over a plastic housing, and each light mounts on a stud pattern on 2 inch centers for a simple bolt-in installation. Electrically, the lights run on 12.8 VDC and draw 0.19 amps in stop/turn mode and 0.065 amps in marker mode, keeping current draw low. The LED elements carry a lifetime LED warranty. This kit is a good fit for anyone replacing worn incandescent trailer lights or building out a trailer's rear lighting from scratch with a matched driver and passenger side set.
