Brakelight bulb flasher This is basically a modified flash circuit on and off a bulb instead of LED. Use a 555 timer IC working as an astable multivibrator.
The blink rate can vary from very fast to a maximum of once in 1.5 seconds, varying preset VR1. The starting time of the circuit is given by: TON = 0.69xC1x (R1 + VR1) second and time off is: T OFF = 0.69xC1xVR1 second You can increase the value of C1 to 100uF for flashing a slower rate up once every 10 sec.we can use this circuit to control bulb of breaklight flasher.
