5/3/19:My electrical nightmare continues. When I turn on the headlights and the truck is running, after a few minutes they began to flash. After searching on this forum, I believe the bi-metallic strip on the headlight switch is opening and closing. I removed the switch and sprayed contact cleaner in it and operated the switch several times. I reinstalled the switch and it seemed to take a bit longer to blink but it still didn’t solve the issue. I spent the next week checking grounds but no joy, so I ordered a new switch from “Classic Parts”.

5/15/19: I received the new reproduction headlight switch and hi/low switch from and was excited to see if it would solve the winking headlight issue I’ve been battling for the last few weeks. The quality looks to be very good, almost an exact reproduction. Installation was easy with my experience of removing and reinstalling the switch several times in the last couple of months.

I removed and replaced one wire at a time so I wouldn’t switch them up. I used a little bit of terminal grease to help prevent corrosion. After reinstalling the switch I reinstalled the negative battery terminal (safety first) and tested it out. I started the engine, pulled the headlight switch and the lights came on and stayed on. I let her run for about ten minutes and all is good. I had also bought a new dimmer switch so I installed that too. Although it was a success, the headlights seemed a bit dim. After reading several post on this forum, I decided to look into installing headlight relays.
