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.

An inflatable flotation device includes one of more pockets for receiving and retaining a lighting element or elements. The lighting elements may be readily inserted into and removed from the pockets so that the user may select the location of the elements. The user may also choose the direction of the light beam emanating from each element. The lighting elements are water-tight in construction and fully submersible, and may be controlled remotely by low-frequency signals that allow the user to selectively activate each element and control the color of its light beam.
