1st before you adjust headlights, lube screws w/like pb, dont strip screws when you adjust, use a good grip on screwdriver(make sure screws arent rusted), to adjust is rather simple, get on a flat surface, with a wall, something light, like white is good, reflects the light, align straight, as you drive down a dark road on a level surface look down lights and adjust till your satisfied. i stagger my setting. dont have it where people at night are flashing hibeams at you, you have lows too high. there are a # of options as far as lights these days. and some good brands out there. i had good luck with cibie before. i have affordable wagner now, theyre bright enough.
