I've only had condensation in the lights after washing the car.
It isn't possible to make a completely sealed unit, even if there are no serviceable parts inside, but there should be a filter and desiccant over the vent - which I think the earlier models skipped hence why so much dust and moisture in the pre-facelift headlights.
Mine had condensation in both when the car arrived new. I waited until a warm day then parked it facing the sun and removed the twist caps at the rear of each, letting them dry out all day before replacing the caps securely. I haven't noticed any condensation problem since.
Did you have led lights or are they bulbs?
I've tried driving with lights on but as said LED lights don't create as much heat as bulbs.
Thanks.
Happens to my car too, left the square cap dangling off at the back for a while but didn't help, might give it another go tomorrow

Hi,
Got lots of condensation in my headlights (led ones) mainly in the drivers side but a little in the passenger side according to the dealer I've spoke to this is normal, so does anyone else have this normal amount of condensation in their headlights.
Thanks.
My 2014 car suffered a cracked rear light cluster after about 4 years and let in water , seems it was a design fault . Eventually replaced it for a new one £100.
unfortunately it Is! i just swapped my 2014 184 fr for a 2019 190 dsg fr , the old car suffered from it and so does my 7month old car !!
it does go away after a few hours! i had no issues with the led lights on my 5 year old car , so can only assume it just happens , i Have never bothered to mention it to the dealer.

Over tightening when new
My 63 plate has it, but nothing I can do. It still works so hopefully it carries on behaving
