Hi all,

My 68 firebird with repop rally gauges has an issue with left hand indicator staying on when the headlights are on. It used to come when the left blinker was on too long then eventually go away but it finally just stayed on.

All the blinkers work just fine, including the hazards. The only other clue i have is if i turn the hazards on with the lights off, both indicators blink together. If i turn the hazards and lights on, the indicators blink alternately but the external blinker lights still blink together.

The front blinker and rear tail lights seem to ground at the housings, so i put an extra grounding wire on the bolts to test but didn't change the issue.

Any thoughts?

I have seen this. And do not recall the exact solution, But my gut leads me to the Dimmer switch on the floor.

Check the bulb filaments, had a 1157 that one filament broke and drop down touching the parking half of the bulb.
