Abstract: A door light frame assembly adapted for use with any of three different types of door construction includes a universal outer frame structure, attachable by screws to any one of three different inner frame structures, depending upon the type of door construction with which the frame assembly is to be used, for securely gripping the inner and outer sides of the door construction around the perimeter of an opening therethrough. The inner and outer frame structures, when assembled, also cooperate to define two separate peripheral channels of different widths for respectively clamping two different-thicknesses of window pane units. The outer frame structure also includes a peripheral groove cut away at two spaced-apart locations therein to define access openings for receiving therein peripheral edge portions of a flexible insert.
