Default Moisture/Fog in headlights normal?

Hi, just discovered today that after taking my Carrera out of the garage and driving for like 45 Minutes around town and parking it back in the garage again, that there was moisture behind the glas of the bottom of both headlights.
My question: Should I worry or is this normal behaviour in fall on these headlights?
Please see attached pictures for reference:

It's normal, the lights are vented and the moisture will evaporate.

My .1 taillights do this as well.
If that's not supposed to happen, please don't let me know as the warranty recently expired (which could be an indicator of brilliantly precise German engineering).

Yes, headlights are vented. Try turning on the headlights to help dry up moisture inside the housing.

I just noticed mine doing it as well on a cold fall night. I’m glad to hear it’s normal.

Both my tails are doing it as well. Are the tails vented? It’s kind of embarrasing.

Yes, both Headlights and Tail Lights are vented and are normal to operate like this. The Tail Lights are more common to see as the engine heat pushes them to vapor up.

The only time you need to be worried and may have a warranty claim is when it starts to form water droplets and does not dissipate over a few days.

Thank you for the confirmation. Yes mine is only a light fogging , no water drops.
