    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.

      Good point, Jim.... I'm off to swap out those 25A fuses in my Hella relays.

        odds are there are 25A fuses in those hella relays because they are anticipating someone running a pair of 100 watt driving lights (200 watts) off of them.
