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.

A water safety garment and apparatus configured to avoid drowning can be configured to permit submergence for a predetermined period of time without inflation. After the predetermined time has passed, the garment or other apparatus can be configured to inflate to help a person wearing the garment float on top of the water to avoid drowning or other potentially harmful condition that may result from being underwater for too long. In some embodiments, a circuit may be utilized to detect the submergence condition of a person wearing the apparatus or garment. Upon a determination that the detected submergence condition has occurred continuously for a pre-determined period of time, an inflation mechanism can be actuated to force the person wearing the apparatus or garment to float to the top of the water.

A Visual Awareness Safety Accessory (VASA) is disclosed for use by a person engaged in watersport/water-based activity. The device may be worn by itself or in combination with a personal flotation device (PFD). The VASA includes a user worn deployable highly visible flag element which is lifted via an attached float when a wearer enters the water. The float raises the flag element well above a user's head whereupon the user can be more easily seen by others using the same waterway. The higher visibility more easily enables location identification of the wearer for rescue, retrieval, and/or collision avoidance.
