Used the lights for the first time last night on my way home from work.
It's really nice. Essentially your brights can be on a lot more, giving you a wider range of visibility, and you can see parts of the beam 'adapting' to the road curves, oncoming cars, and cars you are approaching from behind. I did not get flashed for 'having my brights on' by anyone. The effect is much more pronounced on dark, single lane roads than on multi-lane highways.
Overall, i am happy with the upgrade. the process was super easy. The value is relative and subjective. I think it's a bit on the expensive side for what it provides. Feels like it should have been a $300-$400 upgrade. But in my eyes it makes the car safer. I drive a lot at night and early in the morning for my job. Anything that makes the car safer is worthwhile for me.
