ABSTRACT:
The present invention relates to an improved light bulb socket structure for use in a decorative light bulb series which is provided with a rod on the bottom of the light bulb holder to embrace the electrical wires with the walls of the light bulb socket and to close the opening on the bottom of the socket body in a watertight manner. The inventive socket structure can prevent water or moisture from penetrating into the interior of the socket body and deteriorating the conductor parts of the socket.
