Wiring new interior light

[Tin Hut]

I'm replacing the interior cone lights on my '67 Tradewind. When I pulled the light off I've got one black and one white wire. The replacement light has one black, one white, and a bare copper wire on the back. How should I connect these? Not sure if I should combine the bare copper wire with the white ground wire and then splice that into the white trailer ground. .. or if I just clip it off if it's not needed. It boils down to how connect three wires (on new lamp) to two wires on the trailer. I appreciate any advice from those more electrically inclined. Thanks, Jim

Sounds like you are trying to wire a household electrical fixture into what, the 12 volt system?

It will work but you do know you will need to use 12 volt bulbs.

You can delete the bare copper wire on your new fixture, it is not needed on a 12 volt system.

THanks Chas. It is a 12v fixture, even says so on the inside. I ordered it from Camping World. Guess I'll cut off the bare copper wire and just hook up black to black, white to white, plug in and duck.

The bare copper is ground. It can be screwed to the body but like was said...12v is not a safety issue that requires a ground lead.
