A signaling buoy and method suitable for emitting a light signal over long distances in marine environments. The buoy includes a watertight enclosure having a compartment, an aperture at an upper end of the enclosure for emitting a laser light beam therethrough, a laser light source disposed within the enclosure for generating the light beam, and a battery within the enclosure for powering the light source. Electrical contacts are disposed on an exterior of the enclosure and are adapted to complete an electrical circuit when an electrical short exists therebetween to conduct electrical power from the battery to the laser light source. The buoy is configured to float upright in water with the electrical contacts submersed in the water.
