For the last two years in every snowstorm, this has become a problem. the headlights become built up with snowpack and will not melt due to the efficiency of the led bulbs not producing enough heat. i've tried using the washer fluid sprayers every few minutes to stop build up, but all it does is keep the turn signal area clean, tested multiple different washer fluids as extreme as i can find, even mixing my own washer fluid up made of 50% methanol and 50% isopropyl alcohol. there is no fix for this problem, it is not user error, and it's not a one-time thing, it happens every snow storm involving driving over 25 mph. i've tried addressing it with my local dealer and they told me to reach out to bmw usa, which i've tried with no return phone call. hopefully bringing this to the attention of our department will help me resolve this problem, as it's simply not safe.
