Chris,
Something wrong with your figures. Your headlamp cables using 14/0.012 are awfully skinny, less than 0.002mm2 in CSA . A typical 1mm2 CSA cable as you have for the tail lights is 14/0.3 and is good for 8A. For headlights with 35w bulbs and a good safety margin you'd be looking for 28/0.3 which is 2mm CSA and good for 17A.
I would recommend using a reputable cable supplier like Autosparks. Their website has all their cables listed with safe current ratings
