    I am rewiring some stuff on my truck, including the roof light bar with my KCs on it. Just wondering what guage I should be using for them if I run 2 lights on the same switch circuit. They are 130W bulbs. I use a 30A relay, and havent had any probs, but was just wondering if I am tempting fate by going too small.
    Thanks.
    Mike

    The larger the wire you use the better off you will be. I would say that probably about 12 gauge would be good for 2 lights on the same switch, just make sure the switch can handle the requirements that are demanded of it.

    14 ga is the bare minimum but 12 is optimum. I run all my lights with 8 and 12 ga wire and have no problems. Do try not to snip off to many strands when preparing the crimp them oh yess and relays use relays
