Cant adj. Low beam or high . Low beam has no disatance. When adj about as good as you can get it high beam is in trees and at 30 miles an hr your still over driving the lighted area . When you adj low beam down so it is usable then low beam lights about 3 fet in front of vehicle . And just so you dont judge me as a idiot that dont know how to adjust lights i am ASE MASTERER CERTIFIED. IN AUTOMOTIVE . Ps, i tried halogen bulbs and 2 different brand LED .
