Kevin, X2 on Jerry's advice. This links to my 6 volt headlight upgrade with relays post. The difference is night and day (I know, terrible pun).

Relays I used. I did buy a spare that now lives in the glove box since along with the two headlight relays I have one on the heater blower motor. As you'll likely learn, you can't just drop by Napa or any other parts store and buy 6v stuff anymore.

Good Luck, Ron
