SO, when i turn on my left turn signal it clicks really quickly. Which I know means something is out or dieing.

Well I replaced the front turn signal bulb, and the rear turn signal bulb, and it's blinking super fast. Any ideas?

 

arent there two flashing bulbs in the back? Mine has three...

 

What year Mustang do you have OP? If it's an 05-09, you should have two bulbs in the rear tail lights. Check the extra when you get a chance. That's probably the faulty bulb.

Thanks for the replies guys,

Its an 07GT. The rear assembly has 3 main bulbs and a 4th smaller reverse bulb. When the turn signal is activated, only the outer-most bulb blinks, just one bulb. And I have replaced that bulb and I'm still having the turbo blinker.

Could it be the fuse?

 

i had an issue similar to this on my 06. fast blink. rear bulb wasnt coming on. changed the bulb out...same issue. wasnt the bulb it was something in the wiring. i guess dirt got in the connector and the bulb lost the connection when in the connector. inserted and removed the bulb about a dozen times and it cleaned off the terminals and didnt have any issues afterwards

 

hmmm...i know atleast the middle and outer lights are supposed to blink...somethings wrong somewhere....

 

Replace the middle bulb.

 

The middle and outer lights should be blinking, which is gonna be your problem...

 

Got it, duh. it was the middle bulb. I think what confused me was it was still lighting up when braking (double filament)

so thanks guys.
