ABSTRACT:
An apparatus and method for checking alignment of a lighting fixture comprising a lighting fixture with a housing, reflective surface in the housing, light source in the housing, and a glass lens over an opening into the housing. A marking or indicia is placed on the glass lens in a known orientation with structure inside the housing that is visible from outside of the housing. By line of sight viewing of the marking or indicia, even from a distance away, an alignment of the marking or indicia with the structure inside the housing, the alignment or aiming orientation of the fixture can be determined. This can be used to check alignment of individual fixture, or can be used to check alignment of an array of fixtures, if the array has a known reference correlation to the fixture with the marking or indicia.
