4DZ 002 834-16 Automotive Electronic Flash Relay

   The flasher relay is also called the flasher. Its function is to generate intermittent current to supply the turn signal light, so that the flasher emits a bright and dark signal light to indicate the direction of the vehicle. The flasher is designed with a new type of circuit, which consists of a low-voltage switching circuit, a high-voltage switching circuit, a pulse generating circuit, a diode-amplifying double-tube output circuit and two sets of light indicating circuits. It is installed in the flasher box, and can accurately indicate the driving direction of the car through its control. It has the characteristics of automatic protection. When the circuit is short-circuited, it can automatically stop the work of the flasher and the light bulb, and the driver can pass the flasher. The faults installed on it indicate the working status of the visual flasher, which can be found and eliminated at any time. According to their structure and working principle, flashers can be divided into three types: electric type, capacitive type and electronic type.
The flasher relay is the central control component that sends out the light signal when the car turns and brakes. When the car does not turn and brakes, it can control the circuit to make the left and right rear lights and trailer lights on, and send a braking signal. When the car turns and brakes, it can control the circuit to make the front, rear and trailer lights on the steering side A flashing signal is issued to indicate steering, while the rear lights and trailer lights on the other side only light up and do not flash to indicate braking. When the car turns, it controls the circuit to make the front, rear and trailer lights on the steering side send flashing signals , for turning。
