…the LightGuard System® is.


To reduce needless crosswalk accident, injury and death caused by driver inattention or limited visibility conditions.

Lighted Crosswalk Systems

The federally designated In-Roadway Warning Light (IRWL) system, which we call the Smart Crosswalk™, is a lighted crosswalk system. With this system, a strong street crossing safety measure is established. The lighted crosswalk ensures pedestrian safety with embedded in-pavement signal lights and dependable yellow flashing warning signs. The Smart Crosswalk™ is proven to significantly lower the chances of pedestrian crossing accidents.

A number of in-pavement signal lights are placed across a roadway in front of the crosswalk lines. The lights are activated before entering the crosswalk by the pedestrian. Once activated, the roadway flashing signal lights are focused towards approaching drivers warning that the crosswalk zone is occupied.

Manual on Uniform Traffic Control Devices (MUTCD)

Beginning in 1994 numerous stringent third party studies and testing procedures using LightGuard System Inc.® technology successfully culminated in the acceptance of IRWL enhanced crosswalk lighting system into the Federal Highway Administration MUTCD. The Millennium 2000 edition incorporated IRWL enhanced crosswalk systems into Section 4L, and they have been adopted as a standard across the United States.

United States Utility Patent Position

Michael A. Harrison, CEO of LightGuard Systems Inc.®, invented IRWL enhanced crosswalk lighting system in 1992. In 1993 we received the Federal Highway Administration’s authorization to experiment and in 1994 incorporated the company. In May of 2002 LightGuard Smart Crosswalk™ System received U.S. Utility Patent #6,384,742 B1 for a “system of lights that are embedded in the roadway at crosswalks.” We also hold two additional in-pavement signal lights patents for railroad crossings and signalized traffic intersections.
