All of the sudden my left turn signal is clicking on and off twice as fast as normal. Everything else seems fine. The right turn signal is okay if that matters.

Anyone know what might be happening?

Usually that is a sign of a burnt out bulb either front or back. It could also be the little device that tells the bulb when to click. It is where the click sound comes from. Should be a little silver canister looking thing, about 2" is diameter. I forgot what it's name is.

 

I believe the silver canister thing is called a "flasher", however I'm drinking right now, and could be wrong.

 

More than likely it's a burned out bulb in the left side.

Flashers have had this ability to indicate a burned bulb for at least 35 years.

Either you're young or you haven't kept a vehicle long enough for a bulb to go out. Either of those possibilties is a good thing, I guess.


p.s.
If the Right Signal does double time then, the burned bulb will be on the Right Side.

 

For the record, Yes he is young.

And still 1 year older than me

Well I pulled the bulb and it looked okay. I replaced it anyway and the problem persists. I have changed out flashers before but I don't see one in the fuse box. I do see five relay's and maybe one of them is bad??? I'll check those out next.

Nevermind . . .

When I first pulled the plastic cover off, I reaffirmed that there were two light bulbs in the housing. Headlights activated the top light and the brake pedal and turn signal did nothing. This confirmed to me that the bottom bulb was both turn signal and brake light as I had learned this some years ago. Well changing that lower bulb did nothing. So I popped the other cover off and turned on the right turn signal. The top bulb began to flash???

Well I have now learned that headlights, turn signal and brake lights are all contained in one bulb which is no big mystery as the bulb has two filaments. So now what I want to know is, what is the bottom bulb used for. Testing by myself it appears that headlights, brake lights and turn signal all come from the top bulb and the bottom does nothing. Is that right?

If you're referring to the back tail light, the bottom bulb is more than likely for backing up (you know the little white light that comes on when you put it in reverse).

Ya know. I wanna find one of those really really bright reversing bulbs to bug the crap out of my mom's neighbor across the street.

 

Headlights are on the front and brake lights are on the rear. The headlights and brake lights cannot use the same bulb.

IF you are talking about the rear lights, and IF you mean 'running lights' instead of headlights, then YES- the brake/turn light and running light are contained in the same bulb (For many years it was the very common 1157 bulb, but they use a different number now). The other bulb should be your backup lights.

 

Yes I meant running lights.

It probably is the backup bulb but I thought it went into the red portion of the plastic and not white but I know that isn't correct.

At least the problem is solved.
