Wet roads and weather exposure can quickly ruin a light that isn’t sealed tight. This 2-15/16" round clearance and side marker light is built with a sonically sealed, waterproof lens and housing that form a single unit. That means no cracks for water to creep in and no corrosion to worry about later. It’s designed to stay reliable whether it’s splashed, rained on, or washed down after a trip.
Not every light can handle the bumps and vibration that come with constant use. This one can. Its heavy-duty, long-life incandescent bulb is protected inside the sealed housing, so it keeps shining when cheaper bulbs give out. It’s a straightforward light that just works—bright enough to be seen, strong enough to last.
Setup is simple thanks to its recessed flange design and industry-standard 2-prong plug connection. The flange mounts with three holes spaced 2-1/4" apart on center, giving you an exact fit without extra drilling or adapters. Just connect the plug, secure the light, and you’re ready to go.
Space is often limited where lights need to go. At only 2-15/16" in diameter and 13/16" deep, this round light fits neatly into small spots without sticking out awkwardly. Its compact profile makes it a clean, low-profile option for clearance or side marker lighting where every inch counts.

I looked long and hard for this light for my trailer and etrailer was the only one who had it. I like it all in one piece. George was extremely helpful. They even called the manufacturer and were able to order a part not yet available in the catalog. Thanks to Meriah for her help also.
