I just got done taking the whole lens off. There’s no base, no gasket only butyl tape which isn’t sealing well at all. I’m a bit surprised to see nothing under the lens and 2 drain holes in the top and bottom. I’m wondering if someone screwed up and forgot to put a gasket base in. I’m tempted to get a new light assembly but I don’t want any additional holes drilled in the camper. This is why I was thinking about sealing the whole lens perimeter with Geocel Proflex RV and putty the wire hole from both sides.
