This is a complete system removed from a police vehicle, legally. I tested it and everything works. You get everything in the photos including:

Carson siren controller SA-500 Cruiser, Model SA-500-20 14. This unit controls the Yelp, Wail, and PA system.

Federal Signal Model ES100, this is the siren and it's loud!

The light controller has no name brand on it. There is a model number on the mounting bracket looks like "FP-FEDPA300.

One Motorola 12 volt radio charger, it's dirty, can not confirm it works.

Vertex 171A External Loud Speaker

3 Outlet 12 volt accessory charger

Bosch relay

Bunch of wire  

My disclaimer! This is a real police siren! It was given to me for on of my classic cars but I do not want it. I picture the person buying this would buy it for an emergency vehicle or private security.

You are responsible for hooking it up correctly. I tested it and me and the surrounding neighbors knows it works.

Please email me with any questions.
