Abstract: A lamp can include a low-beam filament arranged in a horizontal reference plane containing an optical axis of a glass bulb, and facing in a direction orthogonal to the optical axis. A high-beam filament can be arranged in a plane normal to the horizontal reference plane and in parallel with the low-beam filament. A pair of inner leads for supporting the low-beam filament can be located in the horizontal reference plane. A pair of inner leads for supporting the high-beam filament can be located in a plane defined in parallel with the optical axis and normal to the horizontal reference plane.

Abstract: A lamp fitting structure having a small depth dimension can include a socket for fixing a wedge-base lamp. The socket can include an insertion portion for receiving and fitting a fixed portion of the lamp therein, a peripheral portion and a rear end portion on the back face, all integrally formed. An opening can be provided which penetrates through from the insertion portion to the rear end portion. The socket does not require an electrical feed terminal for electrical connection, and only performs fixation of the inserted lamp A connector can be fitted into the opening in the rear end portion, for electrically connecting the feed terminal disposed in the connector to a lead wire of the wedge-base lamp. By inserting and fitting the connector into the socket from the rear end portion thereof the fixation between the wedge-base lamp and the socket can be made more secure.

By inserting and fitting the connector into the socket from the rear end portion thereof, the fixation between the wedge-base lamp and the socket can be made more secure. As a result, the depth dimension can be reduced, and a fitting structure that is easily operated can be provided.
