New switch was cheap, amazin Amazon is sending me one out, I am hoping it will help with the dim dash lights, so far no headlight problems.

Back in my misspent youth I had a 64 Sport Fury, and got some "High power headlights" thru JC Whitney, turns out they were aircraft landing lights.

I ground off the alignment lugs and put them in the high beam holes (same size) and was amazed! It would light up from one end of my little town to the other!

On my first long distance trip, across Canada, I had occasion to leave the high beams on for an extended time ... that is when I learned about the circuit breaker built in ...after 1/2 hour the lights would flicker off/on once, then 15 min later again, then about 7-8 min again ...

Finally figured out all I had to do was dim the lights for a couple minutes once in a while and I was good to go, problem solved!

Any other time high beam use was short enough that it wasn't a problem.
