Abstract: A vehicle headlight is arranged to prevent moisture from entering into a lighting circuit and a lighting space. A back cover has a cover main body 19 fitted into a fitting portion 5 of a lamp body 2 and made of resin material and connection terminals 20 embedded in the cover main body (except a part of the terminals) and made of metal material and in which the cover main body and the connection terminals are molded integrally. Component inlaying portions in which electronic components that constitute a lighting circuit of a discharge lamp and are connected electrically to the connection terminals are inlaid respectively are provided to the cover main body. A part of the connection terminals protruding from the cover main body is formed as connector terminal portions of a power supply connector for supplying power to the discharge lamp.

Abstract: A vehicular lamp 1 including a lamp chamber 7, which is formed with a lamp body 3 and a transparent front cover 5 attached to the front opening of the lamp body, and a lamp unit 13, which includes a reflector 9 and a light source 11 and is provided in the lamp chamber 7 so that the optical axis direction of the lamp unit is adjusted by a tilting movement adjustment mechanism 15, wherein a millimeter wave radar device 25 is attached to the lamp body, and a reflection mirror 31 that reflects, toward the front of the lamp, a millimeter wave signal 29 emitted by the millimeter wave radar device is attached to a supporting frame 21 which is a part of the tilting movement adjustment mechanism.

Abstract: A socket includes a housing having a first housing portion and a second housing portion attachable to the first housing portion to cover the first housing portion, a starter transformer and accommodated inside the housing, a central terminal coupled to the starter transformer and disposed inside the housing such that, when the discharge lamp is attached to the socket, a central electrode of the discharge lamp contacts the central terminal. The first housing portion has a base, and a first wall portion extending from the base in a direction in which the discharge lamp is attached to the socket. The second housing portion has a second wall portion which, when the first and second housing portions are attached together, overlaps with the first wall portion such that the first and second wall portions surround the central terminal on an inner side of a peripheral edge of the base.
