ABSTRACT:
A portable light beacon for use on life rafts and the like that has a long life due to a flashing light allowing the battery to recharge and a water sensing switch that once wet remains on. The light beacon comprises a portable battery power source in a water proof container, a flashing light with watertight electrical connections between the flashing light and the power source, and a fluid sensing switch comprising a fluid absorbent composition positioned between two terminals with circuitry to activate the flashing light when an electrical conductive fluid has been absorbed by the fluid absorbent composition to provide an electrical path between the two terminals.
