I rapidly worked the light switch 10 or twelve times and the turn signals came back to life. Thank you DLR.

This reminds me of a story from long ago.

In the 1970's we decided to fix up my grandparents old car.  A 57 Custom.
Rebuilt engine, got it going and it was a car my brother and I shared.
Headlights worked just fine, but the dash lights did not.

Long about 6-9 months later just driving along at night and suddenly for a split second, viola!  DASH LIGHTS in all their glory.

Evidently just pulling and pushing the light switch on did what you said. It cleaned the contacts.

The problem was the switch, I got a new one from Hill’s, all fixed 😊

Headlight switch or turn-signal switch?

had simler problem with 1949 ford truck, the draw on newer bulbs not enough for newer flasher i new style. a way is I installed 1per side of clearance lights some wher out of sight, this gave enough draw to make flasher work. it has worked for 5 years. still works
