US Patent 6842111 Integrated multifunction flasher system

An integrated multifunction flasher system includes a pair of light units, each light unit housing an LED array, LED switches, and a programmed controller within an enclosure. The controllers of the pair of units are interconnected and are additionally connected to the turn signal wiring, the backup signal wiring, and to a manually operated switch. The controllers sense the operation of the turn signals, the backup lamps, and the manual switch and cooperate to generate flash patterns which parallel the turn and hazard flasher signals and which generate alternating strobe patterns in response to activation of the backup lamp or closure of the manual switch.
