Abstract
An emergency signalling system is disclosed that incorporates an emergency signalling device including a light source and reflector mounted for relative rotation in incremental steps in either clockwise or counterclockwise directions. A programmable control unit of the signalling system provides digital signals to a drive source for controlling the speed and direction of the relative rotation. In response to the digital signals, the signalling device executes a variety of different visual patterns. The signalling system can be programmed from a keyboard preferably integrated into a control head mounted to a dashboard area of a vehicle incorporating the emergency signalling system. Virtually any type of visual warning pattern based on the relative rotation of a light source and reflector can be executed by the signalling device if properly programmed.
