ABSTRACT:
A miniature decorative electric lamp assembly includes an electric bulb having dual bare wires inserted into a lampbase, with the lampbase lower end being received in the upper end of a lampholder socket which contains dual contact or blades each connected to an insulated wire. The lampbase lower end has a lower projection portion which is preferably triangular-shaped and extends downwardly to a position between the dual contact or blades of the lampholder socket, so as to preclude any inadvertent electrical short between the blades and bare upper ends of the insulated wires. This configuration also permits any moisture which may enter the lamp assembly to be reliably drained away through openings in the lampbase lower end and the socket member lower end adjacent the electrical insulated wires.
