Just because you never get flashed doesn't mean you aren't blinding other drivers. As an example: The other night I was driving my daily driver(a 2005 Mazda 6) and my passenger side low beam died. Rather than get pulled over and cited for an out headlight, wasting huge amounts of my time between a useless traffic stop and a court visit to prove I had fixed it...I just turned my high beams on and drove around with them on. I knew very well that doing so would negatively impact the night vision of other drivers...but it was just a temporary thing for a few minutes...but lo and behold...no one flashed me the entire 30mins or so and I passed probably a couple hundred cars...it was in the city with streetlights, so the effect wasn't as bad as a dark country road I am sure...but its just an example that just because people dont flash you doesn't mean you aren't blinding them(I knew very well I was)I have LED headlights in all my vehicles except my Mustangs and they ARE next. I never get flashed from blinding other drivers because I chose bulbs without atrocious amounts of lumens and they are aimed correctly. I HIGHLY recommend the 6K color lights. The lines, signs, reflectors, and animal eyes just pop now. It's INCREDIBLE the difference they make.
