How do you adjust the headlights on a 1995 Geo Prism?

To adjust headlights, open hood and look at top outside edges of headlight assemblies. You will see an access hole in each assembly to insert a flat-blade screwdriver. Insert screwdriver until it engages adjusting-gear teeth, then turn screwdriver to turn gear and adjust headlight up or down, depending on which way you turn screwdriver. Turn on headlights and aim car at wall to see which way headlight beam moves when you turn screwdriver.
