A new life saving device used as an emergency signal consisting of a light weight, shirt pocket size, hand powered source of bright, flashing light and high pitched sound which, when carried by persons who become injured, overboard, lost, travelers in an accident, will greatly enhance efforts to rescue them in daytime and avoid the common practice of abandoning search after dark. The light weight and small size are achieved by combining in one device a piezoelectric (ref. Cady) element and a xenon type flash tube principle, but in both derivations and developments somewhat different. The mechanics of hand operation are designed to require minimum hand effort and to obtain good reliability. One piece case adds to reliability. Change of light color at intervals aids recognition as a distress signal. The size, weight and short life of batteries are avoided, as they are not used in this invention.

An emergency signal device comprising in combination, a) a xenon or other gas filled flash tube for emitting bright flashes of light, b) a reflector and a lens for projecting said bright flashes of light in narrow intense beams such that the distance of visibility is multiplied so as to provide an indication over long distances, c) a compressible water proof case for housing said device, d) a segmented multicolor disk between said flash tube and said lens for changing the color of emitted light, wherein squeezing of said case results in rotation of said segmented multicolor disk and supplies power to said flash tube such that bright flashes of different colors of light are emitted over long distances.
