There is a thin rubber gasket around the headlight here. One of mine came loose and broke apart today. The parts manual, sown in the photo below, doesn't show the gasket as an individual part. It appears to be part of the headlight assembly, which is rather expensive. Is the gasket available separately?
It is not available separately but you may be able to get aftermarket lights and replace it with them. I know guys have used the aftermarket lenses to replace the worn OEM parts. Not sure about the part you describe.
