Electric Horn for Bike or Scooter with three siren sounds: ambulance, police car, fire engine and a miniature PA speaker.

Includes bracket for mounting on center bolt of handlebar and a microphone / switch that mounts to back of siren.

Operates on one 9V battery (not included).

Editor's note: I had this same siren on my bicycle when I was a child. It's great fun for children and adults alike! Be sure to watch our little video.
