RC police car with lights and siren

OK   so here is where I'm at with my police car. I can now control both the lights and siren independently from a 3rd and 4th channel on the radio. I used a micro servo to hit a tap switch that cycles through the 5 position siren. #1 is random and cycles automatically through the 4 different tones then 2 through 4 with each tap it will lock on that particular tone until you cycle through them all and back to the off position. The next video will show in detail how this works.
