i just purchased a set of hella 500 driving lights to go on a westin safari bar that should be here within a few days, so here is my question, i was lookin at the instructions and a few things on there are a lil bit vague, such as there are 2 wires leaving the light itself, a black and a blue, i know where the blacks go but what about the blues??? and how about which wire is the high beam? i took a look today and i have a black(ground) a green and a white/green, which do i tap into?? thanx
