I see this a lot on many vehicles it is simply a warning telling you that it is about to burn out. The reason it blinks faster is so that the bulb doesn't too hot for a longer amount of time than it usually does.
If it blinks fast either one of the two lights are burned out or the relay is failing
Turn signal flasher may be defective
Answeri got the same problem.. with a 2000 expedition... darn theft light blinks real fast and the car wont start. help!
That means it time for a new blinker light it is burned out.
Just replace the front bulb, it's no good. That's why the rear one blinks so fast. I'll bet it blinks fast on the dash board too, doesn't it?
It means one of the lights is burnt out or loose and is not working. Turn on the turn signals and get out of the car and see which bulb is not working. Replace that bulb.
They will be noisy and wear very fast.
Most likely a bad flasher
That normally happens if one of your flasher bulbs is not working
bad or wrong bulb is your lights
