I used 28 strand wire which is equivalent to 14 ga. US. Each wire is capable of taking 17.5A. When I ran my calculations I figured that both high beams on would draw 12A and the low beams would draw 10A. I want my fuses to be the weak link in my wiring so my low beams are fused by a single 10A fuse and my high beams are protected by a single 15A fuse. To date I haven't blown either. IMHO your fuse ratings are way high and will not protect your wiring, relays or headlights should something go south. I'd rather blow a fuse than see smoke. Just my 2 cents.
