This is an indication you have a bulb burnt out on the side the blinker is blinking real fast.
If the right blinker is blinking really fast, it means that there is a turn signal bulb on the right side that is burned out. (coulod be either front or rear)
When blinker is blinking too fast it usually means one of your turn signal bulbs are burnt out. Check if bulbs are working. If not replace blown bulb.
If it is not blinking at all or blinks too fast, one of the bulbs is burned out.
It probably means that one of your head or tail lights is about to go out. I have a Ford Taurus and my right blinker started blinking very quickly and within a week, my right headlight was out.
No it means you have your left blinker on. The right bulbs have nothing to do with the left blinker. An incandescent bulb either works or it doesn't. There is no dying out.
It means that the light is about to go out. For example if you turn on your right blinker and it is blinking fast it means the light is about to go out and you should change it.
i don't know if it is a Ford thing, but my dodge did somewhat the same thing... my blinker would flash very fast on the dash and it turned out that my bulbs were out in the rear (maybe that is the problem and your brake lights are connected). When the bulbs burn out the circuit is shorted.
Most blinker circuits do not flash if one bulb is burned out. If the bulbs are all OK then the flasher is probably bad.
It usually means you have a bulb burned out on that side. I can't remember if it's front or back.
often the blinker is made to blink faster when there is a bulb burned out
Replace the signal flasher relay assuming you have physically seen front and rear, left and right signal bulbs flash.
