I've mixed the two circuits together the first is police car siren and the second it's a flasher
 
But the lights are right
Cool but its more like an ambulance siren
I used to make the exact same circuits myself. They're classics. Great job!
Thank you, sir
You're welcome. I even put up an article on this site about a similar circuit to what you have here.<br> <br> <a href="https://www.instructables.com/id/Blink-LEDs-with-Discrete-Parts/" rel="nofollow">https://www.instructables.com/id/Blink-LEDs-with-Discrete-Parts/</a><br> <br> Just the LED flasher, although mine is the PNP version.
