[QUOTE="ionbeam, post: 1249173, member: 277"] Wire gauge isn't what determines the current carrying capacity by itself. The tables are based on the temperature rise of the wire caused by the current flow through the wire. There are 'free air' tables and raceway tables based on the ventilation around the wire. The area around the headlight is pretty well open and should allow the wire to shed heat. If a high current wire were run in an enclosed space or in a tightly packed harness then using a bigger gauge wire would have some benefits. If the wire isn't burned to a dull copper color, if you have soldering skills and if you dress the wires properly before soldering IMO there is nothing wrong with soldering. I would personally solder before crimping. If you are going to crimp, please use a tool that makes a crimp which is selected for the type of connector being used and for the correct gauge wire. I have now seen and heard of a number of burned headlight sockets. It always happens after a bulb replacement, I've never heard of an OEM bulb burning a socket. I have changed a number of bulbs in my FJR and other FJRs and AFAIK, I haven't burned up a socket yet. Next time I have the displeasure of the job, I'll look at the socket and see if the bulb post can fit between the blades in the socket and the housing without going into the socket terminals.
