For trailers that see water, this 2-1/2" round Optronics light is built to stay sealed and working. The housing and red lens are sonically fused into a single waterproof unit, making it fully submersible and safe from moisture getting inside. That means you can use it confidently on wet roads or even when your trailer goes underwater without worrying about leaks or short circuits.
Good visibility matters every time you’re on the road, and this light delivers a bright signal that meets DOT P2 standards. The beam pattern covers 45 degrees to either side of centerline for 90 degrees total, giving plenty of light straight-on for clearance or side marker use. It’s simple too—a replaceable incandescent bulb behind a red snap-on lens that keeps maintenance easy and visibility consistent.
Instead of juggling separate parts, this light integrates a reflex reflector directly into the lens. That built-in design saves mounting space and meets safety requirements without additional hardware. It’s a clean, practical setup that keeps your trailer visible even when the lights aren’t on.
Installing this light is uncomplicated and adaptable. It fits in a recessed mount using a grommet (A55GB or A56GB—sold separately) and connects through an industry-standard 2-prong plug such as the A46PB or A86PB. Once mounted, the open back design allows for easy wiring access, so setup stays quick and tidy.
A tough polycarbonate housing protects the incandescent bulb while drawing just 0.2 amps at 12.8V. At only 11/16" thick, it sits tight against the surface yet handles vibration and weather without issue. With its 3-year warranty and proven cross-reference fit with Uni Bond #SR2500R, Wesbar #223224, Truck Lite #10205R, Grote #45812, and Peterson #143R, it’s a dependable choice for reliable trailer lighting that lasts.
