Great fun little app. I just wanted the signal to flash blue instead of green and it works great.

HOWEVER, I dream of someone taking this to the next level.
Here's the scene:
You're in a bar trying to hook up with a lady. You jokingly tell her you are undercover police or FBI or whatevery. When she scoffs, you whip out your "badge" (which is just a background pic of a badge on your phone.) then push a button to get the blue and red LEDs to flash alternately.
Then say "I'm going to have to take you downtown for a strip search."

At the very least, you got a conversation going!
