Simple Police LED light Flasher Circuit Using 12V Relay 

Police LED light flasher is a simple project that mimics the flashing pattern of siren lights installed on any law enforcement vehicle. It is a simple project that most electronics enthusiasts build first as it is inexpensive & relatively easy to build. So in this project, we are going to build a simple Police LED light Flasher Circuit Using 12V SPDT Relay
The following components are required to make LED Flasher Circuit
1 Relay 12V/5V/SPDT
2 LEDs red/blue/12v
3 Capacitor 16V/1000uF
4 DC Power Supply 12V
5 Resistor 82 Ohm
6 Soldering iron 45W - 60W
Applications
Commonly used in police vehicles to alert the general public.
