i have two 55w offroad lights. what size wire do i need to run to the lights. i think they draw like 10 amps max(110w/12v). im buying a 30amp relay too.
That's a low current product. 16 - 14 gauge should be fine. As for the fuse, make sure it meets the maximum amperage of the lights. Unlike amps, lights will draw the max when turned on.
