etrailer | Feature Breakdown: Optronics LED Off-Road Light Bar

[@miguelvillalpando347]

On this led light can i get my ground from a screw (metal) or my ground needs to go directly to the battery?

Your best ground will be the battery. The problem we've seen with grounding it to a trailer is that if the trailers welds are not great there may be a disconnect between the ground on the trailer and the battery.
