The directions of the cars They are a very useful tool to communicate with other drivers and avoid traffic accidents. Their use is so common that even traffic regulations require drivers to use them.

In fact, if you don’t use your turn signals, you could get fined or fail the driving test of the Department of Motors and Vehicles (DMV).

In addition to signaling which lane a driver is moving into, the turn signals serve to indicate the parking space in which a vehicle will be parked, and in the event of an emergency stop, the flashing light function lets others know drivers that the car is stopped monetarily.

Definitely the use and proper functioning of the turn signals is very important to drive safely. However, with time and use, these can fail or stop working altogether.

One of the most common turn signal failures, is that they blink very quickly when you wear them. In reality, these lights can flash rapidly for a variety of reasons, which could indicate a number of different problems.

Most common reasons why your car’s turn signal flashes very fast.

While diagnosing a rapidly flashing turn signal is generally considered a fairly straightforward procedure, attention to detail is still paramount. A condition of this nature can be caused by one of several different problems.

1.- Faulty turn signal light
2.- Directional focus incorrectly selected
3.- Intermittent module compromised
4.- Damaged turn signal wiring or plug
5.- Hyper flicker induced by a recent update of LED bulbs

Is a fast blinker illegal?

The question of whether the turn signal flashes fast is illegal or not is largely open to interpretation. The Department of Transportation specifies that a vehicle’s turn signal must not exceed a rate of 120 flashes per minute. However, individual state laws may present an even lower maximum acceptable threshold.

So it all very much depends on the exact speed of the blink as it happens and what state you’re in.
