ABSTRACT OF THE DISCLOSURE An improved emergency light means, particularly useful as a sea beacon, comprises a hollow shell containing an air flotation chamber and a water ballast chamber sealed from the flotation chamber. One or more electrochemical cells are disposed in the shell and are activatable by water. Preferably, a reservoir of dry, water-soluble electrolyte is included in the shell. The cathode of each cell is exposed to the flotation chamber and sealed from the water chamber, while the reverse is the case for each anode. A water inlet is provided through the shell and into the water chamber so that when the beacon is placed in water, the cell is activated and the shell floats at a predetermined level in the water. A bulb in the upper transpa- rent end of the shell thereupon emits light, indicating an emergency.
