Installing Optronics OPT58FR Opti-Brite LED Dome Light


Which wire represents positive and what color wire is the ground ????? Also I want to wire all four in series in my cargo trailer controlled by one rocker switch !!!!! Should all the ground wires be wired together and hooked to the switch ????????


Helpful Expert Reply:

I'd be happy to help you with that. The black wire of the # OPT58FR is the power supply, and the white is ground.

You can certainly wire the lamps together so they'll operate on a rocker switch such as # 37212225. You can run each ground individually, or connect them all together and ground them to the trailer frame. You'll want to install the switch inline on the power leg from the 12-V power source.

I've linked to a product description video for the dome light and the switch.
