This is an easy thing, but you need to understand what you're adjusting and where to aim the beam. Take a look in the owner's manual and then peer around the headlight area to understand what the manual says. Generally, headlight adjustment hardware falls into one of three categories: A big knob or nifty electric switch that adjusts the beam for you; smallish but exposed knobs; and the devilishly hidden, hard-to-use screw-type adjusters. Bucket headlights normally pivot around the mounting ears, and have a small setting apparatus, usually below the beam (1). This is among the easier-to-use types; turn the screw clockwise to lower the beam.
