There are two adjustments screws on the top of the headlamp (Allen wrenches) to adjust the vertical and horizontal aiming. The headlamp pattern on the standard cars is rather odd, but lighting can be improved if you're patient. The HID lamps on the late Sport models and some 00 and 01 standard cars were a major improvement.
