Headlamp H4-Ceramic-Socket with heavier wire

Every H4- headlamp Ceramic-Socket I have found has 18 gauge wire in them.
This is really a kick in the teeth when I added the headlamp relays with much heavier wire (for a lower voltage drop) and then I am forced to connect them to the headlamps into a socket that uses 18 gauge wires.

I am thinking of not using a socket and connecting the wiring directly to the headlamps or need a H4-Ceramic-Socket that has heavier wiring.

I am looking and can not seem to find a socket with heavier wiring.

Any suggestions?
