i'm thinking of using all the wiring from some old pilot foglights to wire the halo's to a switch inside the car. its pretty convenient because i have everything including the switch. it's a 12v source but it's 55w. it's just the wattage i'm worried about. think its too much? i searched this and read that the led's are just gonna die in a few months but im trying to make them last as long as i can haha
