ABSTRACT:
A self-contained emergency signal has a base which contains a battery and a high-intensity flash/lamp actuating unit. The actuating unit is electrically connected to a battery and to a high-intensity flash lamp. A switch turns the actuating unit on and high-intensity lamp bursts are displayed through a transparent, translucent, polarized, colored or symbol containing a lens arrangement, or a combination of such elements. The emergency signal may have different forms such as cylindrical, elliptical, rectangular or triangular. In some embodiments the lens arrangements are in telescopic relationship to the base, or may be collapsible to a compact, easy-to-carry device. Exemplary circuitry for use with the various emergency signal embodiments is also part of the invention.
