Lamp Outage Detector Circuit for Car Turn Signal
The O.E.M. turn signal flashing units installed in automobiles have two basic functions i.e. Flasher and Lamp outage detection. These flashers are usually built with an 8-pin IC like U2044B, U6432B etc. which are specifically made for automotive flashers. Designed and Written By Abu-Hafss Circuit Operation These flashers normally oscillate at about 1.4Hz. When a […]
