Beschreibung
Zusammenfassung:	The present invention is directed to an electronic visual distress signal device. In one embodiment, the invention may comprise a waterproof housing comprising: a bulbous portion; a cylindrical portion; and a collar portion. An optical lens may be coupled to the collar portion, extend along a central lens axis, and comprise: an outer lens surface comprising a central outer flat surface located along the central lens axis and an outer convex surface radially outward of the central outer flat surface; and an inner lens surface comprising a central inner flat surface located along the central lens axis and an inner concave surface radially outward of the central inner flat surface. A light source may be positioned beneath the central inner flat surface so that light emitted from the light source passes through the optical lens. A power source may be located within the cylindrical portion.
