Adjusting headlights USA version


To comply with legal requirements, a bubble level (A) well visible from outside is fitted to the reflector at the bottom of the headlight. This bubble level is used to adjust the headlights and check the height adjustment. To allow the side adjustment to be checked, an adjustable slide (B) is fitted to the side of the reflector. This slide is factory-set to the "zero adjustment mark" after the headlight has been adjusted.
