Brake lights flasher circuits
This circuit will allow the brake light was flashing. The default behavior. When the power supply to the circuit, Or tap the brake it. The IC timer IC2 drive current to transistor Q2 and producing oscillator output, pulse signal output at pin 3 to input pin 1 of IC1-CD4024. Count pulse and stops counting after 8 pulses, with pin 2 of IC1 is reset. The transistor Q1 will trigger the IC2, and pin 3 of IC2 change status as well. The voltage drop across R3, the voltage at Pin 7 of IC2-7555.
The Q2 has been a driving bias current, the LED brake lights. Now, tap and hold the brake, the brake lights will flash the set, about 6 times per second. Which is determined by R3 and C3. The distance between each set, is defined by the C2 and R1. The Voltage input to the circuit, used 12 volt DC power from a car at all. The section capacitor C1 as a filter to smooth the flow. Transistor Q2 may be any number SM3180.
The schematic shown here can be used as a circuit for Car brake light or headlight flasher for flashing two 10 watt 12 volt lamps in car or any vehicle.
The heart of the circuit is a 555 timer IC, wired as an astable multivibrator in the circuit. A 2N3773 high current transistor is also used in the circuit and working as a switch and it is derived from the output pin 3 of the IC through a 1K resistor. The IC generates continuous pulses on its pin 3 which makes the transistor switch ON and OFF continuously.
When the transistor will be in the switched ON state the 12 volts from the battery starts passing through it and activate the lamps and in the opposite condition when it is in OFF state then the lamp will also in the off state. This continuous ON and OFF states of transistor makes the lamps flashing. The rate of flashing per second can be controlled by the 100K variable resistor.
