The Bat-Signal is a specially modified Klieg Searchlight that projects a bat-shaped symbol into the sky and used to contact the vigilante known as Batman.
When Batman began waging war on crime, he and Commissioner Jim Gordon formed an uneasy alliance. The latter proceeded to create the Bat-Signal so he could contact Batman in times of need.
