Car Brake Light Or Headlight Flasher

11,203 views

This is a circuit that can be used to flash two 10 watts 12-volt lamps in a car or any vehicle as a circuit for a Car brake light or headlight flasher. It is widely used in cars, motorbikes, and some appliances according to their requirements. Visibility is one of the keys to motorcycle safety. For this reason, people often look for other cars and often “miss” to see motorcyclists.

For this purpose, headlight and tail light modulators (circuits that continuously flash your lights) are common. The circuit’s heart is a 555 timer IC, wired into the circuit as an astable multivibrator.

Car Brake Light Or Headlight Flasher Circuit

Working Explanation

A 2N3773 high-storm transistor It is a bipolar junction transistor based on NPN (negative-positive-negative) power that is primarily used for disk head positioners, high-power audio, and other linear applications. it is also used as a switch in the circuit and is derived from the IC’s output pin 3 via a 1 K resistor. The IC generates continuous pulses on its pin 3 which continually makes the transistor turn ON and OFF.
