Noticed this the other night on the '68
all lights work fine that I can tell.
When lights are off, blinkers work fine.
When lights are on, left blinker will blink like it should for one usage, the next usage it will just stay "lit" with no blinking. Turn lights off, blinker works normal again.
I only noticed this in the dark, but with all the lights off, when I apply the brake and brake lights come on, The dash lights come on and glow softly until I release the brake pedal.
I went to buy a flasher to swap it in to eliminate it as a suspect, but they dont carry anything like it at the parts stores.
Anyone see anything like this before ??
