One thing for us snow belters, LEDs do not provide the heat to keep the lenses free of snow build up when the snow is wet and sticky or when the vehicles ahead kick up spray.
I had a 20 mile trip home and had to stop about every 5 miles to clean the lenses off. What happens as the snow builds up it and turns the lights into like a house diffused light. I could see the light pattern go from focused to a wide beam pattern. After a bit, it looked like a hyper-space jump in the Millennium Falcon. It don't happen all the time, just when the snow is on that "just frozen" state.
This is a pic of what the front of the truck looked like, I had just wiped the headlights. The build up was only about 1/4". I should have remembered from my Jeep days when I had to go to the heated lenses.
