Siren

Italian-made siren, like the type they used in old police cars and as lunch sirens for factories. Note that this does not do a police sound effect, it just screams. Loudly. By turning it on and off (or using a circuit that does it for you) you could have an affordable alternative to spending big bucks on an original siren for your cop car clone. Or use it for your car alarm. Works well. Red paint is starting to come off but not as bad as photo makes it look. 12V.
