Headlight Flasher
+September 98 Project : 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.
