Police Lights Circuit with 555 and 4017 IC

This circuit uses a 555 timer which is setup to both runn in an Astable operating mode. This generates a continuous output via Pin 3 in the form of a square wave. When the timers output changes to a high state this triggers the a cycle on the 4017 4017 decade counter telling it to output the next sequential output high. The outputs of the 4017 are connected to the LEDs turning them on and off.

Police car light system

Today Im going to give you a wonderful schema diagram.Most of you ask about police car light systems.So I thought to give you a police car light system schema diagram.Here I have used two ICs one is IN4017 and the other one is  40106.Here I have used only blue colour LEDs If you like to add any other colour you can add them.I think after adding this schema for your car you can attract others. 
 

Note 

# Build this schema on a P.C.B
# Dont use more than 6V Read More
