Some maint. manuals like Haynes and/or Chilton's have a procedure that will get you "into the ballpark" on aiming your headlights. The best aiming can and should be done by a decent auto body shop. A LOOONG TIME AGO Abra advertized that they will align headlights for free...but I doubt anyone does it for free anymore. Best bet is if they let you sit in the car while it's done so beams are adjusted for your weight.
