Abstract
Potential disadvantages of the enhanced emergency hazard warning lights set forth in U.S. Pat. No. 7,352,278 are overcome by adding a lamp that beams its light rearward toward approaching traffic, is located approximately midway between and above the horizontal alignment of the rear turn signal lamps, thereby forming a triangular flashing emergency hazard warning signal that cannot be discontinued or otherwise disturbed when the vehicle's brakes and brake lights are simultaneously operated.
