Patent ID: 7192156

Claim:
A waterproof indicator light comprising: an upper casing formed of a light-transmissive material, said upper casing having a light refracting surface on an exterior thereof, said upper casing having a hollow containment space therein, said upper surface having a connector at a bottom thereof; a lower casing formed of a light-transmissive material, said lower casing defining a hollow containment space therein, said lower casing having a connector at a top thereof engaged with said connector of said upper casing, said connector of said lower casing having a sealing ring therearound so as to form a liquid-tight seal between said upper and lower casings; an illuminating module having a circuit board and a plurality of light-emitting diodes, said illuminating module positioned at a juncture of said upper and lower casings; a plurality of disc-shaped batteries positioned in said hollow containment space of said lower casing; said plurality of disc-shaped batteries selectively connected to said illuminating module so as to provide power to said plurality of light-emitting diodes; a conductive component extending in said hollow containment space of said lower casing, said conductive component having an upper C-shaped member in planar contact with and electrical connection with said circuit board and a lower connection point, said lower connection point being in contact with a terminal of one of said plurality of batteries, said conductive component having a conductor extending between said lower connection point and said C-shaped member; and a step-up means positioned on said circuit board, said step-up means for increasing on output voltage of said plurality of disc-shaped batteries to a pre-determined value.
