Headlamp adjustments in a workshop or garage does not always lead to good lighting. In many cases mechanics set the cutoff too low, just to be safe to avoid glare.
Furthermore, often only too high cutoffs are corrected because there is a lack of consideration that low cutoffs mean short beams.

Knowledge among automotive mechanics about the importance of vertical adjustments can be assumed. On the other hand, the horizontal adjustment often is neglected. In most cases the 15-degree asymmetrical part of the beam is set too much to the right – lighting up areas away from the road. Wrong aiming to the left is somewhat more rare because it can cause glare. Many mechanics concentrate too much in the avoidance of glare instead for setting the focus to good vision and the correct aiming.
