Troubleshooting Utility Trailer Light Dim on Right Side


Retired trailer left side light works great. Right side is dem not bright


Expert Reply:

It sounds like the right side of your trailer may have a bad ground connection. I recommend visually inspecting your wires for missing insulation or fraying and then using a tester to see if you are getting the same voltage on each side of your trailer. If the voltage is the same, you most likely have a bad ground connection which is often found in the mounting of the lights themselves. You want a bare metal to metal connection free of corrosion or debris. You may also want to use some dielectric grease # 11755 to keep moisture and debris out of your connections.

If your voltage is not the same, I recommend replacing the wire as needed with # 16-1-1 sold by the foot. I've attached some wiring articles to help.
