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.

Vehicle headlamp

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.

Vehicular lamp having simplified structure and reduced condensation

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.

Vehicular lamp having waterproof cover

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. A hole from which the front end of the bulb for the auxiliary lamp is projected is formed in the horizontal extended part, and a lens for the auxiliary lamp having a lens (prism) step area formed thereon for guiding light beams from the bulb in a given direction is mounted in the hole.
