Installing New Trailer Light with 2 Wires in Place of Trailer Light with 1 Wire

Question

Question:

I am trying to install a 2 wire LED license plate light, to replace a rusted out 1 wire light assembly. The problem is that the entire trailer is aluminum. How can I ground this light?

Aluminum trailers are known for issues when it comes to grounding.

You can accomplish this by joining the individual grounds with a butt connector like # DW05745-10 to the one main ground wire.

Another option is to install a simple junction box like # 38656 where each individual light's ground can be joined. Then connect to the main ground that goes to the trailer connector. Use ring terminals # 44-5310A to make the connections inside the box.

Run the white wire on your trailer to the mounting bolt of the new license plate light. Your current light ground through the mounting hardware so you'd just need to connect the ground wire there and you'd be good.
