Abstract

Abstract A buoyant body of foamed polyurethane equipped with an illuminating light which is directed downwardly into the water when the body is floating on the water''s surface. A smaller signal light at the top of the body serves as a warning light. The assembly may be held by a handle formed along its upper end. The light emitting face of the assembly is sealed with a recessed, light transmitting face plate to provide a treated, directional light beam of white light set in a thin annular field of blue light to provide improved illumination in highly reflective environments. Power is preferably supplied from a remote source through a flexible electrical line and a three-way switch is included on the assembly to energize the illuminating light and/or the signal light. The buoyant body has a low center of gravity and is equipped with an annular recess along its outer surface which cooperates with the inset area over the face plate to increase floatation stability when the body is in an upright position.
