I had similar symptoms once with my '70. I tried everything. I was complaining about it at a party, worried that I wouldn't pass my next brake inspection. A fellow there who turned out to be a very experienced mechanic went out to the car, pulled the bulbs and wiped out the sockets brisquely with his handcerchief. Then he rubbed the light posts and put it all back together. Problem solved. It was a bad ground.
