A motor vehicle headlamp having an improved mounting structure of an extension reflector provided between the front lens and the reflector of the headlamp. An extension reflector, formed separate from the lamp body, is provided between the reflector and the front lens. The front end of the extension reflector is held adajcent to or in contact with the inner surface of the front lens to minimize the gap between the extension reflector and the front lens, and the rear end of the extension reflector is spaced from the reflector so that the extension reflector cannot interfere with the opening end portion of the reflector during the aiming operation of the reflector. The headlamp may be combined with other lamps in such a manner that the other lamps are arranged on both sides of the headlamp inside a single lamp body with the headlamp and other lamps juxtaposed with one another, and light shielding walls are provided for the lamps on both sides of the headlamp to cover the gaps between the reflector and the extension reflector.

Motor vehicle headlamp

A vehicular headlamp having an inclination measuring unit mounted on portions of an aiming screw which extends rearward from reference member. The inclination measuring unit is interposed between a reference member and the rear end portion of the aiming screw, protruding rearward from the reference member. The inclination measuring unit includes a cylindrical transparent casing surrounding the aiming screw and fixed at one end to the reference member, a cylindrical base accommodated in the transparent casing in such a manner as to be rotatable when the aiming screw is turned, a ring-shaped slide member engaged threadably with a male-threaded outer cylindrical wall of the cylindrical base, the slide member being slid axially by rotation of the cylindrical base while being prevented from being turned relative to the transparent casing, a coupling member extending through an opening formed in the transparent casing into the cylindrical base to engage with tapered engaging portions of the cylindrical base and with outside surfaces of the aiming screw to couple the aiming screw with the cylindrical base, and a scale formed on the transparent casing and a reference line formed on said slide member to indicate the amount of relative displacement of the inclination member. With the invention, unlike the prior art, it is not necessary to provide a fine adjustment mechanism for adjusting the scale following initial zero-point adjustment.
