Turn Signals

[89LT1FIREBIRD]

I have a problem with my turn signals when I turn on my headlights. With my headlights off, my turn signals blink normally with no problem. When I turn my headlights on, my turn signals start blinking very slow. Does anyone know the cause of this?

Check all your lamp sockets for corrosion and check the grounding for you lighting.

You could also have a bad flasher try a different one possibly a HD one .
