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
