Fans for the headlights, who knew?

[Its her Bronco]

My wife is the proud owner on a 2021 Bronco Sport Outer Banks (with Outer Banks package including the moonroof). She order it March 2021 and received it September 2021. Flash forward to yesterday when I was checking her oil and discovered the fans for the headlights They were running). She had been home about and hour and I did not start it but assume the fans came on when I opened the door. I checked a few minutes later and the fans were off. How we owned it this long with out noticing the fans is blowing my mind. My question is who else did not know and is there anything else like this we dont know about?

I noticed it the second day i parked it in my garage in May 2021. Drove me nuts that it would kick in when i would go and open the door to get something out. I accepted it now lol.

Yeah it's part of the moisture and heat management if I recall. Any time the lamps are activated the fans kick on for a few minutes. It's trivial.

They come on just for opening the door and contribute to draining the battery even if the headlights are never turned on makes no sense to me.
Getting battery saving mode from drain if I don't start the car for only 2 days.
