Abstract: The present disclosure provides a light source mounting structure including a bulb mounting hole provided in a reflector, a socket fixture configured to be fixed to the bulb mounting hole, and a bulb including a bayonet flange configured to be inserted into the bulb mounting hole and, when rotated, to be engaged with the socket fixture. The socket fixture is integrally provided with a snap fit that is capable of being elastically deformed and configured to be engaged with the bayonet flange. The bulb is easily mounted due to the elastic deformation of the snap fit and is also suppressed from being detached. The snap fit is integrally formed with the socket fixture, and thus, the number of components may be reduced.

Abstract: A vehicle headlamp including a discharge lamp, which includes a light source, and a cap that holds the light source. The vehicle headlamp also includes a reflector, which includes a light reflecting part and a lamp holding part formed contiguously with one end of the light reflecting part. The vehicle headlamp also includes a socket connected to the cap, which supplies drive current to the lamp. The socket includes a case that holds a structure disposed therein, and a connection portion, which is connected to the cap and which protrudes toward the cap from an opposite surface of the case facing the cap. A conductive member is mounted on the lamp holding part to transmit noise generated when the lamp is turned on and a conducting portion is formed on the opposite surface of the case to surround the connection portion. The conductive member and the conducting portion are connected.

Abstract: A vehicular lamp having a combination lamp structure in which the reflectors for a plural number of lamps and an extension reflector are provided in a lamp body, wherein a reflector for at least one lamp of the plural number of lamps and an extension reflector are constructed as a single body. Of the reflectors for the lamps, the reflector fixedly mounted on the lamp body and the extension reflector are preferably constructed as a single body. A specific reflecting portion for reflecting light from a bulb toward a lens area located apart from the bulbs of the lamps is formed as a part of the reflector. For example, a lamp of which the lens is partly extended to the side of a vehicle body, and a specific reflecting portion for reflecting light from the bulb toward a lens area of the lens extending to the side of the vehicle body is formed as a part of the reflector of the lamp.

Abstract: In a vehicular lamp with a waterproof cover, a cylindrical upright wall extends along the circumferential edge of the opening of the lamp body into which a bulb socket supported by the reflector is inserted. The waterproof cover for waterproofing the opening is made of a watertight elastic material. The inner portion of the waterproof cover is in close contact with the circumferential surface of the reflector or a bulb socket. The outer portion of the waterproof cover is fitted to the upright wall in a state such that the upright wall is sandwiched by the outer portion.

Abstract: A vehicular headlamp assembly with an auxiliary lamp which is small in size and does not require the provision of a special mounting space. A lamp chamber is defined by a generally capsule-shaped lamp body and a transparent front cover applied to the front opening of the lamp body, a reflection or projection lamp for forming a normal running beam, a projection lamp for forming a passing light beam, and an auxiliary lamp are disposed side by side within the lamp chamber, and a mirrored-surface inner cover having an opening through which the front end of the projection lamp is exposed. A bulb for the auxiliary lamp supported by the lamp body is disposed at a position located aslant on the side of the projection lens when viewed from the front in a state such that the bulb is directed forward. The lower edge of the inner cover corresponding to the bulb is substantially horizontally extended to form a horizontal extended part.
