Before turning left or right, the car driver needs to turn on the car's turn indicator so that the driver of the approaching car can take corresponding preventive measures. If your car's turn indicator fails to light up for some reason or other reasons, it will cause a traffic accident. If your turn indicator does not light up, this circuit will sound an alarm to help you protect against any accidents.
