ABSTRACT:
A connecting structure of an electric bulb includes a socket, in which the electric bulb is mounted, and a connector having a terminal received therein. The connecting structure also includes, fitting into the socket, a first lead wire and a second lead wire connected respectively to both ends of a first filament of the electric bulb, and terminal portions, formed respectively at extension portions of the first lead wire and the second lead wire which extend outwardly from the electric bulb. The terminal portions are connected to the terminals respectively when the socket is fitted on the connector. When an inner wall of the socket abuts against a front wall of the connector, an electrically-connected condition of each terminal portion and the corresponding terminal is maintained, and a power source and the bulb are electrically connected together, so that the bulb is lighted. The connecting structure may include more than one filament in the bulb.
