There can be so many reasons for that, for starters as you mentioned, different wires/system. I know i don’t need to “look” for the wires in the windscreen, they’re immediately visible every time i get into the car – and even on video.
In regards to the “they’re brighter but dazzle less”.. Brightness is the property that determines the “amount of dazzle”. A brighter headlight will always dazzle more than a less bright one if you get hit by it, beam control doesn’t matter if it shines directly into the cabin. That by itself wasn’t the argument anyway, i certainly am not complaining about LED headlamps, i wouldn’t give ours up for anything.
I am talking about the halo they create when hit by light. It doesn’t even need to be headlights, when it’s raining a normal street light creates reasonably sized halos.
edit: to reiterate, i went to the optician because i thought it’s my eyesight going, and it’s not. My wife has the same problem, too.
