67 Sport Fury Turn Signal Issue

[SFury67]

I recently replaced several blown bulbs in the dash (e.g. turn signal indicators, brake system, high beam indicator). Now the right and left turn signals interior and exterior work when the headlights are turned off. However, if I have the headlights on and move the turn indicator lever for a right turn, the headlights flash on and off with the right signal lights flashing correctly. It does not occur when the left signal is on.

Any ideas on the cause would be appreciated.

Maybe corrosion in a connection? Follow back from the head lights, and start testing, disconnecting connectors and use a test light to see if headlight circuit is flashing as you move back

If all worked correctly before you changed the bulbs I would remove them 1 by 1 while testing the turn signals again. It may be a pain, but you just might be able to find out what happened.
