ABSTRACT:
A visual signaling device having interspersed arrays of red/amber/green LED signal lamps and a center flashing strobe lamp. A side mounted joy-stick type toggle switch on the housing is operated by the user's thumb to provide the control of the signal lamps. One position of the joy-stick button operates an on/off switch, and the other three positions each operate one of the three color arrays. A separate strobe light switch is provided adjacent the toggle switch. The housing of the signaling device is bowl-shaped and held in the palm of the user's outwardly extended hand. A strap extending around the back of the hand provides assistance. A battery pack is recharged through a standard socket for connection through a cord and utility plug to a power source.
