Squad car light flasher circuit chart

An extremely intriguing circuit the squad car light flasher.

The principle driver of the circuit is the 555 clock chips and squad car light flasher having the light streak on the other hand and simultaneously having vibrating streak.

The figure above you can see the schematic outline of a straightforward LED police flasher with two prevalent 555 incorporated circuits. Both 555 work as astable flip-flop, each with an alternate recurrence. Their yields are associated with hostile to parallel two gatherings of LED s. Underneath the vivified chart is additionally given to comprehend it with greater clearness.
