I'm not an expert but you need a minmum gauge wire. I know I had to have my wiring replaced with a thicker gauge but I can't remember what the size was, I had my Autoelec do it.
Someone else's recommendations "Ideal you just want a good quality multi-core cable in the minimum gauge recommended for your current power requirements. You lights are 55W each right? I would use 14 gauge at a minimum for driving both of these and 12 gauge to give you some room if the need ever arises.
Multi-core copper cable is pretty low on resistance as it is and over the short distance that you are going to get to the driving lights
, the effects of a voltage drop are hardly going to be noticeable. Even more so with yourself having HID lights as those are electronically controlled and even if they got 10V, they would still output full power by drawing more current.
