If you get your hands on a police car for any reason, you want the means to fiddle with its obvious extra features, don't you? Maybe you do and maybe you don't, but you can in almost any other open-world game with a police car, so why not here? With this mod you'll get new options that will allow you to toggle sirens and spotlights off and on with any police car.
