Headlight wiring need to be replaced

[herve_g]

Hi guys,

I've bought a used set of headlights for a HID conversion.
The outer lenses were bad, I've done some polishing and they're much better.

Next step, checking the internals. I noticed that most of the wiring is getting bad (cracked or very brittle). I have no choice but to replace it all.

My question is:
What gauge wire should I use ? would 14 be enough?

Thanks,
Hervé
