The bulb is bad or about to go bad. I put a new one in and still had same problem. Did a 1/8 turn twist the socket to get better connection but bulb broke off exposing wire. Super glued it but stlll not flashing or now too fast. Got another non- defective bulb and wala fixed!
More than likely you have a burnt out bulb at the front signal light, rear signal light, or brake light on the right side.
If your blinker is blinking at a faster rate than normal, it usually means that one of the bulbs is out. For example, if the left turn signal blinks faster than usual, check either the front or the rear left turn signal. If both turn signals seem okay, check the front left parking light. (this is the front orange light that is on when your headlights are on)
u need to replace both bulbs
It means your turn signal bulb burnt out.
If you turn on your 1999 mustang v6 car and the right signal light stays on and doesn't blink and you switch the car off and then the left signal light stays on without blinking, then you need to see a mechanic.
A right handed person has to send a signal from the right side of the brain to the left side before the signal is sent to the body. A left handed person gets the signal direcly on the left side of the brain, therby left handed person have slightly faster reflexes.
One of the bulbs is burned out on the left side. The left front or rear bulb is burned out. Same problem with left side blinking rapidly and right side blinking normal speed. Both left side bulbs are lighting up, however?? Replaced both anyway and the problem still exists.
Either you've got a broken bulb on the right side, or you've got a bulb with the wrong wattage on the right side, or there's some damage to the wiring harness on the right side.
You have a failed bulb on the right side.
Normal cause is failed bulb.
bulb is burnt
Defective turn signal switch.
