Abstract: A method of warning a person of a first vehicle entering a defined boundary. An electronic safety marker is provided proximate the defined boundary. The electronic safety market has an electrical current source, a transmitter, an impact sensor and electrical circuitry interconnecting the electrical current source, the transmitter and the impact sensor. The electronic safety marker is deployed from a second vehicle proximate the defined boundary. A signal is transmitted with the transmitter after the electronic safety marker is deployed. A receiver is positioned a distance from the electronic safety marker. The receiver is capable of receiving the signal. The electronic safety marker is struck by first vehicle. Transmission of the signal is ceased when the electronic safety marker is struck by the first vehicle. An alarm is emitted from the receiver when the receiver ceases receiving the signal to warn the person of the first vehicle entering the defined boundary.

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 further includes a transmitter for sending a signal to a receiver. Upon impact with the safety marker, the signal ceases and the receiver, equipped with an alarm, triggers either or both of an audible or visual signal.
