The Bat-Signal is a fictional distress signal that shines a light into the sky with a shadow in the shape of a bat to call Batman and Robin when there's a crime happening or when James Gordon has a lead on a case. Gordon, Harvey Dent, Harvey Bullock, Hamilton Hill, and Barbara Gordon have access to the machine. Many spoofs of the machine are made in many television shows.^[1]
