Brakelight Stop flasher

Posted on Feb 15, 2013

This is basically a flasher circuit modified to turn on and off a bulb instead of a LED. It uses a 555 timer IC working as an astable multivibrator. The flashing rate can be varied from very fast to a maximum of once in 1.5 sec by varying the preset VR1.

The ON time of the circuit is given by: TON= 0.69xC1x(R1 + VR1) second and the OFF time is: TOFF= 0.69xC1xVR1 second You can increase the value of C1 to 100uF to get a slower flashing rate of upto once in 10 sec.
