Normally this happens when one of the bulbs is burnt out. Make sure all bulbs are working.
Check the back signal light. Usually if the front blinks fast the back is out or need to be replace. Vice versa
Change the front turn signal light bulb. It's bad.
your rear bulb is blown - replace the bulb The turn signal blinks fast because the bulb is going out. That is also why the others dont blink.
check your bulbs, this happens when a light bulb is burnt out good luck
I would look at the REAR signal light on the same side of the car. It is probably not blinking at all and the bulb needs to be replaced.
Usually when the turn signal indicator in the car blinks fast is because one of the bulbs is blown. Check to make sure all your indicators are working when you turn on your left blinker. There are at least 3, front.. mirror... and rear.
often the blinker is made to blink faster when there is a bulb burned out
This is probably due to a faulty relay switch. The switch needs to be replaced so it will blink in the right timing.
One of the front blinker bulbs is burnt out. Replace the bad bulb and the blink should function normaly. you have a front right turn signal bulb that is burned out. the resone it blinks fast is there is less load on the flasher .
The new bulb is already burned out, not seated properly in its socket, or you replaced the wrong one. Get out and look at the signal lights while they are blinking fast. Either the front or rear light is not blinking at all. That is the one that needs to be replaced.
That's usually an indication of a burned out bulb.
The bulb that is not illuminating, is installed incorrectly. Take it out, and replace it with a new one, making sure the nubs on the socket are in the right slots.
