It is a specially modified searchlight with a stylized emblem of a bat affixed to the light, allowing it to project a large bat symbol onto cloudy night skies over Gotham City.
The signal is used by the Gotham City Police Department as a method of contacting and summoning Batman in the event his help is needed, but also as a weapon of psychological intimidation to the numerous criminals of Gotham City. A civilian organization employs a liaison to the Gotham Police Department to activate the Bat-Signal, owing to a legal precedent in which the police department would have to take responsibility for Batman's investigative tactics, should he be operating as their agent.
