Are headlights supposed to be heated?

Fog lights make a short but wide light, shaped like a lentil....not helpful, especially not on the bumper.

I experience the problem of clogged headlights every time it snows in Scotland. Probably not helped by almost all of our snow falling in the temperature sweet spot mentioned before. It is a work vehicle also used for responding as a volunteer in emergency situations. I don't have the luxury of staying at home when it snows. Would be great to have a cheap road legal solution.......

maybe split the windscreen washer tubing and add a headlight washer or an aftermarket one

I guess if you’re out in the middle of nowhere driving in that narrow window of temperatures keeping the snow and freezing ice off with heated lamps is one thing, but I agree with your prognosis that in most driving conditions, it’s going to be traffic with modifiers on the road being thrown up by other people‘s tires and that it’s not so much temperature as in dirt and gunk buildup. That’s why I started a thread about a headlight cleaner washer. That seems like it would take care of both conditions.

I wonder if that sort of gear would lead to headlight glass cracks due to the temperature change? Similar to what some are saying is happening with the windscreen.

Aren't the light lenses plastic?

Polycarbonate. Always. Because in front lights only polycarbonate can withstand.

Unfortunately polycarbonate tends to discolor. Here you find one of the quality features a LED light can have: a high quality polycarbonate with a high quality UV protection coating will be fine 16 years and longer. Bad quality will discolor or show small cracks in the coating after three years.

I say 16 years because the oldest Nolden LED headlights are around 16 years old, now and they are still fine.

Cheap ones, three years old:
