Decided to replace the Landing Light Lens because the one I installed earlier had a 1/8 inch gap between the lens and the skin leading edge at one side. Trimmed the replacement lens to size and sanded the edges. Match-drilled the holes in the lens and countersunk them. Installed the lens and used new screws since the slots in the heads of the old ones have widened (loosened). The new lens fits much better than the previous one.
