I was thinking of buying from mustangplus, mustangsunlimited, mustangbarn, or one of the other restoration parts suppliers.

That article is helpful, hopefully I can find that tool they use. Thanks again, there is a reason I have been a member for 5 yrs!

Once you get your lights working properly, consider installing some relays. I have thus setup. You can also make your own. It will take the load off of the switch as well as supply more voltage to the bulbs giving you brighter lights.

That is a great idea too, I'm putting that on "the list"

If they're blinking off and on intermittently, I'd agree about the switch.

But you also said they're going brighter than they ever have before. That can only be caused by high voltage at the headlamp and THAT can't caused by the switch. The switch can reduce current through high resistance contacts, but it certainly can't manufacture any more volts. I know you checked your battery voltage but still, my bet for the overly-bright lights is an intermittently sticking cutout relay in the regulator (I'm assuming it's an electro-mechanical regulator, not a solid-state unit).

I have to replace the dash light bulbs anyways, so doing the headlight switch at the same time isn't too much extra work it seems. I have a regular stock external regulator, and the lights DID use to dim (they do not anymore...). I figure eventually I will want to slowly rewire my car so doing the switches now saves me any future hassles.
