Moisture in headlight

I noticed this morning that there is a lot of moisture in the driver side headlight and a little in the passenger side. Is this normal or something I should have the dealer look at? Please see attached pictures
Thank you all.

Take it to your dealer. They will look at it and see if there is a leak, a failure in the seals or if the dust cover was removed.

Yes its normal when there are significant temp changes. Your amount was actually not bad. If water puddles inside the housing then its a problem.
