Review on 🚛 8pc 2.5-Inch Amber and Red Round LED Trailer Clearance Marker Lights - DOT Approved with Reflector Lens, Grommet, Flush-Mount, Waterproof IP67 - Marker Lights for Truck Trailers by Randy Holt

The light itself is great with a few bright LEDs compared to the 3 LEDs you usually see in TSC or Northern Tool. However, and perhaps just an installer error, it is impossible to mount it in a standard 2.5" hole using the supplied grommet without damaging the rubber or cracking the light. So instead of turning a hole to make the included bushing and an easy fit I went to Northern Tool and bought the replacement bushings they carry that fit right into the OE hole with the marker light in place. I would just use the 2.5 -Buy light on it yourself next time and bought the rubber grommet separately.
