I've got a couple of questions about wiring for my lights. I've got 4 hella 500's I'm putting on the roof and I'm trying to decide whether or not to stay with 2 relays (1 per pair like the installation manual says) or 1 relay for all 4.
If my calculations are correct (4 55 watt bulbs = 19amps), then using 10ga wire, instead of the 12ga wiring harness that comes with the lights, and a 40amp relay should be more than adequate to power all 4 lights and simplify my wiring.
Any comments from those in the know??
