JFP I'm sure it does. It definitely won't hurt. A lot of vehicles offer this as a higher end option or a standard feature in luxury vehicles; automatic self adjusting/leveling/cornering headlights.
My understanding, sorry if I am wrong since I am from a city, is if your high beams are already on along with your LED/Xenons, how dark can that country road be? You're not running halogens here. It's 1.5 degrees here.
I can't picture how the self leveling is a necessity. I don't step on the pedal if I can't see what's in front of me. Is that just me?
