Pulled it off a Litronic headlight.
My other Litronic headlight does not have one and I don't really care for them so I'm selling this one.
The rubber has slightly softened on both ends and there is a single crack (shown in photos).
However, most of it is intact and has not turned to goo.
Sold with 2 screws that help to hold it in place.
Asking price is $70 shipped obo.
