[QUOTE="2020Raptor, post: 1592148, member: 39638"] Thanks very much for joining in. I want to have two methods of turning on my light bar. 1. Upfitter switch 2. High beams (solid state relay, per a different thread) My understanding is that use of the appropriate diode will prevent backfeeding the unpowered leg. That is the goal, unless there are additional considerations of which I am not yet aware. Which is what I discovered here while performing my due diligence. Apparently, you cannot just use any diode labeled "12V". Googling this topic will make me want to toss the light bar in the trash, ha ha. Thus my desperate plea for assistance here on the forums. :dogpile: [/QUOTE]
