If you (not you personally) are so concerned about lighting up the road in front of you just drive with your high beams on all the time. Same thing.
Maybe you should Google “beam cutoff” to learn why you are so wrong.
Well then, that fully explains why we're switching to flourescent bulbs and why we can only buy low volume toilets.......Experts need not be questioned I guess.
Another product of new-age America, "official" studies were performed and found an item to be safe, then it must be safe. As for me, I say trust but verify. And my personal verification is that the those bright blue lights blind me all the time, just as much as do high-beams, and they are dangerous. I also hear this from other drivers as well, so I'm far from alone. (Just a note, I wonder if those 'scientific' studies included asking what actual drivers thought about oncoming xenon lights in the dark of night? Isn't that the real way to confirm it?
A couple years ago I owned a sweet 1999 Cadillac Seville with non-zenon headlights and those lights lit the road up nearly like daytime, and with a very wide span from left to right. They were amazingly efficient. No one ever flashed their high beams on me while driving in my Caddy because they thought I had the high beams turned on, but I will flash those zenon lights all the time, because they most certainly do blind you.
My next car was a Buick LeSabre Limited whose standard lights weren't quite as good as the Caddy, but were still strong and efficient. Conclusion: Xenon lights are just another expensive toy, a marketing gimmick to make money from fools who like the blue hue, the increased visibility, and are stupid enough to believe they're not blinding the poor drivers approaching in oncoming traffic. Or if they are aware it doesn't matter anyway. This is, after all, modern America, land of "the self".
