This is a Warning Light and Marker Light Circuit Diagram. A flashing light of high brightness and short duty cycle is often
desired to provide maximum visibility and battery life. This
necessitates using an output transistor, which can supply the cold
filament surge current of the lamp while maintaining a low saturation
voltage. The oscillation period and flash duration are determined in the
feedback loop, while the use of a photo transistor sensor minimizes
sensitivity variations.
