Interesting turn signal problem
 

76 targa.
All the signals work fine as expected until I do left turn.
It blinks once ok with the left arrow but then the second and so one shows both arrows flashing but slightly faded. Bulbs are ok outside.

I have ordered another blinker but wondering if anyone encountered this problem before.

Thank you.

Hi there
you have a bad ground the one of the units on left.Check the front or rear light assembly.
