Abstract: A warning illumination system adapted to be mounted on a motor vehicle (automobile, truck, motorcycle, etc.). In a preferred embodiment, the system is designed to project a single or a pair of light beams forwardly and angularly from the front of the vehicle. As contemplated the beam(s) is projected a distance of fifty to one hundred feet in front of the vehicle and at a horizontal angle across the vehicle which may range from forty-five to sixty degrees. For maximum effectiveness, it has been determined that the beam should be projected at a vertical angle so that it intersects the road at approximately a thirty degree angle. The thus projected beam reaches forward and across the lane of traffic, making the extreme end of the beam visible to an oncoming driver approaching from a hidden curve or blind corner. The beam is visible to the oncoming driver critical seconds before the approaching vehicle is visible.
