Hi Everybody
I am working on an automotive turn signal flasher circuit.
Usually, the original flasher unit installed in a vehicle is IC-based which detects lamp outage i.e. when any of the 3 indicator lamps fail, the flashing frequency is doubled.
I am thinking of using a 555 flasher system or a 2-transistor flasher system and using some comparator IC to detect lamp outage.
I came across the attached schematic while googling, maybe this can be of some help.
I shall appreciate your assistance.
