Trailer wiring

A dead license-plate lamp is a small wiring job that still fails inspections and night stops. Check the bulb or LED, the ground, and the feed from the taillight circuit.

Quick fix

Test power at the lamp with the lights on. Clean the ground. Replace a cracked lamp housing that lets water in. Tie the repair into the same check as side markers.

Canada note

Salt and moisture kill these lamps early. Dielectric grease on the connector helps after a clean repair.
