1. An automotive lamp assembly, comprising:
- a stud and collar assembly includinga stud,a cap located at an end of the stud, anda collar disposed on said cap; and
a lamp housing that is welded to said collar,wherein said stud extends about an axis, wherein said cap radially extends from said stud, wherein said cap includes an outer peripheral surface, wherein said collar is defined by an inner peripheral surface that correspondingly-interacts with the outer peripheral surface of said cap to prevent rotation of said stud about the axis, wherein said collar is defined by a weldable outer peripheral surface, andwherein said lamp housing is further defined to include a rib that defines a weldable inner peripheral surface, wherein the weldable outer and inner peripheral surfaces cooperate to provide a weld interface that joins said stud and collar assembly to said lamp housing.

Abstract
The subject invention relates to an assembly and method for attaching a stud to a lamp housing that decreases the overall size of the automotive lamp assembly. The apparatus has a collar molded over a stud. The collar attaches the stud to the lamp housing by being shear welded to the lamp housing. The stud is prevented from rotating about its longitudinal axis, so that it can serve to mount the lamp housing to an automobile.
