AD Headlight switch
I have a couple of headlight switches that came with the truck. Is there a way to tell 12v vs 6v? Or does it even matter?

Re: AD Headlight switch
it doesnt matter, much. the 6v contacts will be rated for twice the current of the 12v switch, but either will handle 6 or 12v in my opinion.

Re: AD Headlight switch
Put your headlights on a relay! Then you dont run many amps thru the switch...

Re: AD Headlight switch
Thanks for the responses. I planned on a relay for lights.

Re: AD Headlight switch
If the switch is good and you run relays the switch will think it has ended up on easy street because it will only be carrying the load to trigger the relays. The only real issue anyhow is how the resistor handles the dimming of the dash lights.

Re: AD Headlight switch
Don't mess around with something as important as headlights. spend the $40 on a new 12 V switch from classic parts.

Re: AD Headlight switch
As much trouble as I have had with old switches over the years I can't argue with that one at all. Old switches usually already have pretty well worn or possibly corroded contacts and tend to fail at all the wrong time.
