Installing Ground Wire on Trailer Lights


Hello! I am struggling extremely hard with what I am assuming the only issue with hooking new brake lights onto my pop-up camper the ground connect.. Ive read through the instructions, watched youtube videos, even phoned in people with more experience. I cant seem to figure out why there still isnt a connection when I plug the lights into the car.


Expert Reply:

The LED Clearance or Side Marker Light w/ Reflector - Submersible - 4 Diode - Rectangle - Red Lens # MCL76RB is a clearance light and not a brake light. The clearance lights only have one power input and one ground, where tail lights will have a running light wire, a turn and brake combination wire, and a ground.

Most of the time the ground wire goes from the trailer connector to the frame of the trailer and then each light also will ground to the frame. I recommend making sure the ground connection is bare metal to metal and clear of corrosion and debris.
