Trailer Incandescent Side Marker Light Red 126RW

This Incandescent Oblong Trailer Sidemarker and Clearance Light features a single bright incandescent bulb and a durable red plastic lens.  The bulb is replaceable through the rubber grommet in the back of the light, which acts as a shock absorber so the filament doesn't break during bumps while trailering.  The Light has 2 wires, 1 goes to power and the other to ground, but it doesn't matter which is used for which.  The Lens is also a snap on design so it can be replaced if scratched or otherwise damaged.
