Batsignal

"You're a hard man to reach."

- Harvey Dent

The Batsignal is the modified searchlight used for summoning Batman. Like the Batarang, Batmobile and Batcave, it is not referred to by its "bat" prefix name in the films. At the conclusion of The Dark Knight, Commissioner Gordon destroys it in front of the press, symbolising the disavowment of Batman's activities.
