Tonight was the first time driving my Cruze after dark. Something seemed a little off with the headlights during twilight, so with the help of a family friend I did an impromptu alignment. At 25 feet from the front bumper the cutoff from the headlights was raised by approximately 4", or ~2 full turns of the adjuster bolt (8mm head) Driving later, the headlights performed very nicely, with a good throw and excellent illumination on low beam. The high beams weren't that great, so I'll back off the lights by 1/4 turn, for a total of 1.75 turns of the adjuster.
Our Honda with its 9003/H4 headlights needed the exact same thing done to it right after delivery, so this wasn't my first time adjusting single-bulb headlight systems.
If your stock headlights are annoying you with their lack of illumination, try adjusting them up by 1.5 complete turns. The results may surprise you.
