Abstract:
A flotation device includes a pocket formed within its hollow body in open communication with an exterior surface thereof and a hollow housing mounted in the pocket. Illuminatable fiber optic strands are disposed in a predetermined pattern within the hollow body each having a light receiving end thereof protruding into the pocket through a wall thereof in an air impermeable manner and further into the housing. An illumination source is mounted inside the housing in close proximity to the light receiving ends of the fiber optic strands and a power source is also disposed within the housing and operatively coupled to the illumination source. A multi-colored filter pane is mounted within the housing intermediate the illumination source and the receiving end of the each illuminatable fiber optic strand. A switch is provided and is manually operable by a user to operate the illumination source causing the strands to emit light.
