  • Illuminated emergency signaling device
    Publication number: 20030132852
    Abstract: A battery-powered emergency signaling device including a housing which encloses a battery pack disposed for providing power to the device. The housing can take on a variety of shapes. At least one light emitting diode (“LED”) pulsed by an electronic circuit, which LED is powered by a battery within the battery pack. A race is disposed about the housing for reflecting light received from the LED. The cover includes support members disposed between the base plate and the cover for providing strength to the device. An anchoring member is attached to the housing, thereby allowing the device to be mounted on a traffic cone. Also, the device includes a switch that turns the device on or off, thereby prolonging the useful life of the device.
