Wig-wag (sound stage)
From Wikipedia, the free encyclopedia
This article is about the wigwag movie stage warning light. For other uses, see Wigwag (disambiguation).
A wig-wag is the red light (also known as a "red-eye") near each door of a motion picture sound stage. It flashes to indicate that cameras are rolling inside the stage and all people and vehicles outside should remain quiet. A flashing wig-wag is accompanied by one long buzzer when the cameras start rolling, and two shorter buzzers when cameras stop rolling.
