Abstract
An electronic lighted safety marker system used by emergency responders to warn motorists of the presence of an accident scene ahead on or beside the roadway is provided by the invention. Such safety marker can be deployed individually or in groups by the emergency responder along the perimeter of the accident scene and ideally ahead of it along the roadway to provide adequate warning to approaching motorists to avoid the accident scene. The safety marker contains a power source, a light panel, a protective shield for the light panel, and electronic circuitry for controlling the operation of the lights in a predetermined frequency or pattern, and may be automatically actuated and self-righting when it is dropped onto the ground or other hard surface. The safety marker can also contain an incursion warning system against incoming vehicles, an early warning radar transponder for sending a warning message to such incoming vehicles, a GPS location detector and transmitter for providing the location of the safety marker and its associated accident scene to a central dispatcher, and a gunshot sensor for detecting the occurrence of gunfire around the accident scene and its location to provide that information to the central dispatcher.
