The present invention comprises a pivot stud with an axis of rotation in the
horizontal plane for use within a visual optical aim light assembly. The axis of
rotation of the pivot stud defines an axis of rotation about which the light assembly
may be rotated so as to properly aim the visual optical aim light assembly. The
pivot stub does not allow rotation about planes other than the horizontal plane.
According to one embodiment, the pivot stud comprises a ball and socket of a generally
ellipsoid shape.
