doesn't work well in my experience. now I typically just leave my mirrors all the way out and up when driving at night, so the headlights never hit my eyes from them

I can see everything I need to from the rearview and turning my head. it's not like you can see anything using the side mirrors at night when somebody with LED headlights is behind you anyways, all you see is a giant flare and you can't even tell if it's in your lane or the next lane or how close it is

LED headlights are literally making the roads less safe by decreasing visibility and awareness
