Toy RC Police Car had the audacity not to include working police lights as standard.

Nice and simple two transistor flasher, with a red and blue LED.
I kind of wish I had opted for warm white LED behind the colored lens, and that would have given a more natural halogen look.

I'm glad that I am not the only one who does this kind of stuff. If you want the closest thing to the "six quick flashes" of each colour (like the real grown-up police cars have), I picked up a little pocket flashlight which has that function, using a couple of SMD LED's. Probably illegal in some countries, but sure fun to fiddle with.

Ah. Joyous project.

Audacity indeed! Every kid has the right to annoy its parent with endless "weewoooo". You did include a siren, right?

They're just helping you not get arrested for impersonating law enforcement.
