I would use the Sealed, 6-1/2 inch LED Clear Oval Trailer Utility Light, 10 Diode, item # BUL72CB, along with the Rubber Grommet for 6-1/2 inch Oval Trailer Tail Lights, item # A70GB, and the Trailer Light Mounting Bracket for 6-1/2 inch Oval Trailer Lights, Steel - Black Powder Coat, item # BK70BB. These items should work for you and have a specific mounting bracket that is not available for the Thinline Sealed LED Utility Light, item # UCL65CB. Be sure to unplug the trailer connection before entering the water.

You will need to wire the lights to the backup light circuit on the vehicle. If you have a factory installed 7-Way connector then the vehicle connector should have the backup circuit connected to the center pole. If not you can wire the center pole on the 7-Way to the reverse light circuit. I would use the 10 Gauge Blue Primary Wire, item # 10-1-1 and a quick splice, item # 562. Use a circuit tester, item # 3808 to find the reverse circuit behind one of the tail lights.

If you have a 4-Way at the rear of your vehicle then I would use the 5-Flat Vehicle End 72 inch Wiring Harness, item # 20016, and the 5-Flat Trailer End 48 inch Harness, item # 20017, to complete the wiring needed for the reverse light circuit.
