Turn Signal flashes rapidly, but bulb is fine

Hey guys, I have an 07 JK and yesterday my left turn signal started rapidly flashing. Of course this is a tell tale sign of a dead bulb, however when I inspected the lights, both the front and rear bulbs were illuminated.

But the rear left turn signal would not flash, and the front left signal would flash rapidly. The right side is fine.

I was wondering if anyone could tell me what the problem is and how to fix it. Thank You! -Travis

I had it happen in a car, a wire had pulled out of the socket. Might check and make sure everything is secure & snug on your connector.

It sounds like you flasher needs a tranquilizer to slow it down! (JUST KIDDING)!

I think that you have lost your ground to the light assembly. Normally there are two things that will cause a flasher to speed up, either a burned out bulb, or your light is not grounded......

Check to see if both of your brake lights work. The directionals and brake lights are on the same filament.

The tail light does not use the same filament as the turn signal/brake light. Turn on the signal and see if the light flashes. If it does not, replace the bulb and your rapid flashing should go away.

A while back my jeep was doing this, same symptoms as OP. bulbs were good but if I remember correctly one burned out shortly after it was going crazy. replaced it, it freaked out a few more times, and eventually it just went away.

Replace the bulb in the rear. Mine did same exact thing last week. Replaced bulb, problem solved.
