I would think so. My lights (in an unusual AG config) are actually clear lenses that pass through the wall, with a rubber gasket between them and the liner. The light (12volt) fits into the opening in the lens from the outside and can be removed for maintenance without touching the water. The lens then is permanent. Here's a link to it:
