Just got my car for slightly over a week. Today has been drizzling and for our locale, the temperature is warm and humid.

Are these condensation on the inner surface of the head lamps (both sides) normal?

My dealer told me that it is normal for mercedes after I sent her the pictures.




I don't get these on my Lexus, subarus or saab....

I've got the same condensation almost every time I wash the car. It will go away after I drive for a little bit.

I have had it. Goes away.

Logically speaking, if there is enough moisture within the housing to form condensation, wouldn't it means that either the headlamp seals are not doing the job or there are excessive moisture trapped during the manufacturing process?

Anyone have any idea on the design of the headlamp units to understand if there are some valve that allows air pressure equalization as well as one way moisture release?

This is normal. The lamp housing allows a certain degree of condensation to prolong the life of the bulbs. there is a membrane behind the housing to manage moisture. safe level of moisture that is
