Abstract

A waterproof light bulb holder is provided that includes a cap having a light bulb engaged in one end thereof, the cap and bulb being received within a bore formed in one end of a base. A plastic cork having two opened holes for receiving the electrical wires which are inserted into the base with conductors coupled thereto is disposed within a frustro-conically shaped bore found in an opposing end of the base. The plastic cork provides a secure and waterproof engagement with both the base and the wires, to prevent water from infiltrating into the base and resulting in a short circuit.

a cap having an open first end for receiving a light bulb therein, said cap having an opposing closed second end with a pair of through openings formed therein for respective passage of a pair of leads of the light bulb therethrough;

a base having a first bore formed in a first end thereof for receiving said second end of said cap therein, said base having a second bore formed in an opposing second end thereof, said second bore having a frustro-conical contour; and

a plastic cork having a frustro-conical contour for being sealingly engaging said base within said second bore, said plastic cork having a pair of openings formed therein and adapted to tightly engage a respective pair of wires extending into said base.
