Headlight Flasher

Headlight FlasherThis circuit was requested from an email. It will allow your car headlights to flash on and off at the same time or it will cause them to flash alternately. The circuit is based on the 555 timer. It is used in the astable mode.

The 555 timer output will go high for an adjustable period of time and then turn off. It will then repeat the procedure.
The time is adjusted by R1. To hook up the circuit to your car you must locate the positive wire from the fuse box to the headlights. Cut the wire and insert the relay contact and bypass switch. The bypass switch will allow you to bypass the relay contact for normal headlight operation. In the alternateing headlight configuration you must cut the positive wire to each headlight and wire in the relay contact.
