Abstract: An adjusting and support apparatus for a lamp unit is provided which has a horizontal adjust and support mechanism in which the load bearing and adjusting functions are separated to provide an improved support structure which does not rely on a cantilevered arrangement. In addition, a vertical adjustment mechanism which can be secured to any unoccupied position on the outside surface of the lamp unit is provided, thereby imparting greater flexibility to the design of the front portion of the vehicle.

Abstract: A lamp-within-a-lamp headlamp unit includes an inner lamp body which is adjustably received within a first end of an outer lamp housing. A second end of the outer lamp housing defines a lens through which light is projected from the headlamp unit. The inner lamp body sealably receives a lamp bulb through a bulb access opening in a first end of the lamp body which is accessed through the first end of the outer housing. Light is projected from the second end of the lamp body which can be open if appropriate focusing reflectors are provided adjacent the lamp bulb or closed by an internal lens. An area surrounding the second end of the lamp body is sealed to the outer lamp housing by a flexible inner seal which extends between the lamp body and an inner portion of the outer lamp housing. The flexible inner seal permits the inner lamp body to be adjusted relative to the outer lamp housing which is secured to a motor vehicle for aligning or aiming the light beam projected from the headlamp unit.
