Headlight blink with turn signal?

Question

Hi I have a 95 mustang and the drivers side headlight blinks when I put on the left hand turn signal

and the fog light on the same side burned out so I replaced all and same thing any guesses ????

Answer 1

Does it blink on and off or does it just fade a little.  If you replaced the light, are you sure you replaced it with the correct type?  I know that if you replace a headlight with one that is brighter or stronger than recommended, you could run into problems like this.

You're probably not an idiot and didn't DO that though, so I would take the car to autozone and get the battery and alternator checked to make sure they're maintaining a constant voltage when your electrical system is experiencing a bit of extra load (such as when you put on your turn signal) and see if that doesn't solve your problem.  

Answer 2

Sounds like you have either a bad ground for the turn signals or you have a multi-function switch going out.  The multi-function switch is your turn signal/cruise control arm.  The older mustangs were notorious for those going out.
