We have a heated front screen in the XC40. First time I”ve had one and I find it useful on occasion. I’ve never experienced the effect you mention Rene and have noticed modern LED headlights have much better beam control than older cars and even though they are brighter they dazzle less.
That’s technically true, but not here where i live. If you live in a “flat” area, yes. LED headlights have a sharp “cut-off”, but we live in a hilly (rural) area with a lot of crests. This inevitably leads to the problem that you constantly drive through the beam when someone else comes over the crest.
LEDs only dazzle less because of mentioned sharp “cut off”. If they shine straight into your car/face (which they do constantly here), they’re worse than any other beam, be it Halogen or Xenon. That leads to said halo effect. I certainly am very happy that our next car does not have a heated screen.
That was just an off-topic rant, really, though, since i did drive through a foggy night yesterday, constantly getting blinded.
