I have somehow missed the boat on these rubber dust caps. I've got LEDs in my low beams and the stock dust caps don't fit. I looked around before and apparently missed these as a potential solution. So they are just open. Sometimes I get a lot of moisture in there. Has anyone used this type of rubber dust cap plug? I see ones that cover all, and some that allow the heatsink to come out through a hole in the middle.
