I just finished my power steering conversion and as a final touch while I had the bib off I decided it was the right time to finally do the old powering the headlights off of relays mod that has been posted here on mud.
I was blown away with how good my lights work now, and I'm still using standard Sylvania H6042 lamps. I was going to go with the Silverstars but now I don't see an immediate need for them, maybe I'll get them down the road.
Price list:
40 amp relay 2 qty, one for high beam, one for low, $9 each at Napa.
30 amp circuit breaker $4 at Autozone.
High heat resistent headlight connectors $9 at Autozone. I got these in case I want to use different lights later on.
Wire and Misc. connectors ~ $10.
I would have honestly say that my high beams damn near rival the Warn rectangular off road lights that I used to have.
My 41 year old wire harness from about mid fender forward was in bad shape, literally disintegrating, and was a total clusterf**k. I don't even know how my turn signals were still working. Right turn + wire had one strand of the copper wire providing power

The grommets on the fenders for the turns were decayed and split, hence the reason for the turn wires being sliced and diced.
So this project added another night to to the steering conversion but it was worth it. The lights work ridiculously good, and I lessened the risk of the 40 being a electrical fire hazard - priceless
