Headlight wire sizes

[chewychevy67]

I am rebuilding my gmc 4 bulb wiring harness from the firewall to the battery. I'm charnging to led headlights and my harness looks OK but looking at the headlight wires they seem really tiny. I'm also adding relays to my headlights so I'll be making a custom harness for the head. Shod I be upgrading the wire size on this side of the harness on the other side of the relays to the lights or will the stock wire size be just fine?

Stock headlight bulbs draw somewhere around 6~8 amps max. Doesn't take a big wire to carry that current. Look at the size of the wire from the dim/bright switch. That is carrying the current for all four bulbs. No reason for the individual bulb wires to be larger then that one.

Probably worth while to make sure the socket contacts are clean.
