What are these?

[Chaz]

I know they go into the headlights but I am just curious as to what they do. I have searched everywhere and can't find any info..


Also I am wondering what part number for the clips that holds the door trim pieces (the black piece that runs down the middle of the door.)

As far as I know they let moisture/heat out.
