What causes a turn signal to blink rapidly?
A bad bulb is by far the most common reason that a signal blinks faster. This is because a bad bulb alters the resistance in a circuit, sending a different current through the blinker. Otherwise, inspect each turn signal bulb for signs of failure such as broken filament or dark, clouded glass.
Is a fast blinker illegal?

How can you tell if a turn signal flasher is bad?
The most common symptom of a bad or failing turn signal / hazard flasher is hazards or turn signal lights that do not function. If the flasher breaks or has any internal issues it can cause the lights to malfunction, or not respond at all when the turn signal lever or hazard light button are pressed.
How do you diagnose a turn signal operating problem?
Check for a blown circuit fuse.
- Verify that circuit connections are not loose, corroded or unplugged.
- Inspect the wiring harness or terminals for the rear section of the circuit.
- Check for a bad connection between the turn signal switch and the flasher or between the flasher and the ignition switch.
What causes turn signal to blink rapidly?
Bulb Failure. The main reason why turn signals start blinking really fast is a bulb failure in the head lamp. When the bulb fails to work properly because it has been damaged or broken, the resistance switches adapt to the sudden change by making the light blink repeatedly in a very fast manner.
Why is my turn signal blinking faster than normal?
There have also been cases wherein the turn signal lights blink faster than normal. This problem is typically caused by either a malfunctioning bulb or a broken or grounded combination switch. If the bulb fails to work properly, the resistance switches adapt to the sudden change by making the light blink repeatedly.
What does it mean when the turn signal is flashing fast?
Even when you encounter a bulb failure in the headlamp then, also the turn signals start blinking fast. This mainly happens during the broken or damaged bulbs, when the resistance switches start acting abnormally by flashing the light repeatedly at a great speed.
Why does turn signal FLASH Fast?
Another reason why turn signals flash fast is if the car isn’t supplied with enough voltage. Most commonly, when there is a bad combination switch, voltage supply drops instantly, thereby causing the indicator to blink really fast.
