Anybody run in to headlight housing getting moisture in the lens ?

 

Years ago here I think I remember a post about this, I think it was due to bad seal at the headlight bulb to housing.

 

Water enters through an opening behind the housing. That is where the lamp is inserted.
Difficult access, headlight in the wing. If the lamp is not screwed in all the way, there is a way for water. Lockers allow dirt and water to pass through.

Another option is condensate. But how to deal with it and where it comes from, I do not know.
