Last weekend I installed these LED lights on a trailer bed. They look great and are super easy to put together with some strippers, heat shrink, zip ties and a cordless drill. I used #8 screws to mount them. The white wire is grounded (a pin on the 4-wire trailer connector) and the black wire must be connected to the brake, turn signal and parking light wires. I had a question about the size of the lead wires and answered it after I received the lamps. Unfortunately it was removed because the reviewers of the question have no idea what wire gauge means. Connection wires 16.
