Abstract:
1. In a motor vehicle having an emergency 4-way flasher circuit with 4-way emergency lamps, a CHMSL and a brake light switch, an enhanced hazard warning light system consisting essentially of: (a) means for transmitting pulsed electrical current from the 4-way flasher circuit to the CHMSL when the circuit is activated, thereby simultaneously flashing both the CHMSL and the emergency lamps on and off, and (b) means for transmitting a steady electrical current from the brake light switch to the CHMSL whenever the vehicle's brakes are engaged, whereby (1) when the flasher circuit is activated, the CHMSL is automatically and simultaneously flashed on and off together with the 4-way emergency lamps, (2) when the vehicle's brakes are thereafter engaged, the steady electrical current from the brake light switch automatically overrides and suppresses flashing, and initiates steady illumination, of the CHMSL while the emergency lamps continue flashing, and (3) when the vehicle's brakes are disengaged, simultaneous on and off flashing of the CHMSL together with the 4-way emergency lamps is automatically resumed, the flashing cycle of the CHMSL with the 4-way emergency lamps not including white light during the off periods of such cycle.
