I am planning on buying some LED Halo's, and I was wondering how to wire them independently with a switch maybe on the inside. I don't have fogs, so I was assuming wire the switch to the ignition (no clue where that is if you could show me) and then wire the Halo's to the switch? Would that be the best way to do it?
