Distinctive hazard flash patterns for motor vehicles and for portable emergency warning devices with pulse generators to produce such patterns

A hazard alert flash pattern, as in 1), for motor vehicles, for portable emergency flashers, for illuminated emergency warning triangles, and for electric lighted substitutes for pyrotechnic flares, which flash pattern is non-uniform and different from and distinguishable from the flash pattern used for vehicle turn signals.

A hazard alert flash pattern, as in 1) and 2), which includes a series of any number of short flashes, separated by short off times, all followed by a longer pause or off time, after which the cycle repeats.

A hazard flash pattern, as in 1), 2) and 3), consisting of three short flashes, separated by two short off times, all followed by a longer pause or off time, after which the cycle begins again.

A hazard flash pattern, as in 1), 2) and 3), consisting of four short flashes, separated by three short off times, all followed by a longer pause or off time, after which the cycle begins again.

A hazard flash pattern, as in 1), 2) and 3), consisting of five short flashes, separated by four short off times, all followed by a longer pause or off time, after which the cycle begins again.

A pulse generator which produces a distinctive hazard flash pattern, as in 1), 2), 3), 4), 5), and 6), and in automotive applications also produces a standard turn signal pulse.

An electronic flasher system which uses a microprocessor to produce a turn signal pulse, and also to produce distinctive hazard flash pulse patterns, as in 1), 2), 3), 4), 5), 6), and 7).

Electronic flashers as in 1), 2), 3), 4), 5), 6), 7) and 8) in applications to operate incandescent, bulbs, light emitting diodes, and other light emitting devices.
