head light wireing

[4ford]

when wiring the headlights 12 volts. do I or should I use a relay? do the wires coming from the relay to the lights have a smaller wire?

thanks for your help!!!

If stock 6V wires are present they are plenty large enough for 12v. Relay, your call. I have 12V halogen headlights operating off my 70+ year old stock '41 switch and never had a problem. A relay would take some of the load off the headlight switch if that's a concern.

If someone wants to put up a diagram showing headlight [12volt] wiring with a relay Im for it!

Here's a collection of diagrams I've used. dw

thanks guys for the diagrams... now do you really need the relays?? sounds like no but would be nice to have them in place?

No, relays are not required.

I used relays because the existing wiring was inadequate to carry the load so I used it to trigger the relays which I powered by new, heavier gauge wire. There are lots of ways to skin a cat. dw
