Abstract:
An emergency signalling system for mounting to a vehicle that generates two or more moving beams of light, the system comprising in combination: at least first and second signalling devices for generating the two or more moving beams of light; each signalling device comprising a rotatable reflector driven by a motor; a memory containing data for a plurality of visual patterns, each pattern being made by one of the two or more moving beams of light upon rotation of one of the reflectors; a controller responsive to a user interface for selecting from the memory an appropriate one or more of the plurality of visual patterns and transferring the selected one or more patterns to a variable field of the memory; and a means responsive to the patterns transferred to the variable field of the memory for collectively controlling the motors of the at least first and second signalling devices to generate a desired emergency signal comprising the two or more moving beams of light.
