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.

  1. I can’t read the IC numbers on the bright pink background of many of your circuits. Many descriptions do not include the part number. The circuit cannot be built without this information.

  2. Please could someone help me to make my car third brake light that use leds give a puls and then stay on until brake pedal is relesead.
