Abstract: An enhanced motor vehicle warning system provides flashing lights in response to the sounding of the horn. The driver can either enable or disable the system. When the system is enabled and the horn is sounded, latching and time delay relays close to provide power to various lamps and in particular to the high beam lamps and back-up lamps. This power, through the latching relay, is provided through a flasher so that these lamps provide a visible flashing light signal in synchronism with the flasher for the predetermined time period set by the time delay relay. Parking lamps may also be energized, if they are off. But preferably not through the flasher.
