Old incandescent lights can be dim, fragile, and power-hungry. This thinline LED fender light uses two powerful diodes that shine bright with less draw—just 0.048 amps at 12.8V. The amber lens faces forward and the red lens faces rear, keeping both directions clearly visible. Because it’s all solid-state, there are no filaments to burn out, and the LEDs last up to 50 times longer than old bulbs. You get a brighter, cleaner glow with less power wasted.
Water damage is the enemy of trailer lights, but this one is built to take it on. The red and amber polycarbonate lens and housing are sonically sealed into a single waterproof piece. That means it’s fully submersible—perfect for trailers that see water or constant road spray. The sealed body keeps moisture away from the diodes and circuit board so this light stays reliable season after season.
Space can be tight along a trailer fender, which is why the Thinline Series design works so well. At only 3-7/8" long, 1-1/4" wide, and 7/8" thick, it tucks neatly onto the fender without sticking out or catching gear. The surface-mount setup uses bracket A65B (sold separately) and fits standard 1-prong or 2-prong plugs like A65P, making installation simple and clean without extra drilling or wiring headaches.
Visibility from the right angle matters for safety. This light carries a P2 rating, producing a 45-degree beam to either side for a total of 90 degrees of coverage. It works well as either a clearance light or side marker light depending on where you need visibility most. Paired with its durable housing and long-life LEDs backed by a lifetime warranty, it’s a simple, dependable lighting solution that just works.

No issues. Still works great after multiple launches and being completely submerged in water.
