I was on the highway in my Mustang on the way home, and I noticed that the left turn signal was fast. Fine, just a bulb. Then it went back to normal.. Weird.
Changed lanes again.. fast.. changed again, normal..

Got home and checked all the bulbs, they were all fine while braking and "turning". Cannot reproduce the problem..

What could it be?

 

It could be a bulb filament about to go bad or a flaky ground connection.

 

Blinker fluid low?






J/K. What Art said.

 

Short in the flux capacitor?

 

Be careful that pony may "Beam you Up", thanks for the heads up.

 

I cannot reproduce the problem this morning. All bulbs fine. I will report back. Thanks!

 

yea wouldn't worry about it too much, probably have a bulb with a filament thats a little funky and will probably blow soon, no biggie
