Abstract
Abstract A headlamp and integral mounting assembly having three peripherally spaced integrally formed mounting means, which cooperate with headlamp support means to provide three suspension points from which the lamp is pivotally mounted for independent adjustment from two of the points for limited pivotal rotative movement about a pair of coplanar, orthogonally related and intersecting axes, one of which axes is contained in an axial plane passing through the geometric center of the lamp unit and the other of which axes is displaced from the geometric center and located outwardly of the lamp unit.
