HEADLIGHT AIMING
The aiming of the sealed-beam headlights is
effected by projecting the upper beam of each light upon
a screen or a chart at a distance of about 25 feet from
the headlights as shown in Fig.
9.
The truck should be
squarely lined up with the screen.
The vertical lines on
the chart mark the distance between the center lines of
,the headlights and are equally spaced from the center
line of the chart.
A horizontal line should be placed on the chart at a
level of two inches below the height of the headlight
centers above the floor.
Each headlight must be
adjusted so that the hot spot of the beam will be
centered over the point of intersection of the vertical and
horizontal
lines
as
shown
in
Fig.
9.
IMPORTANT:
In some states, the above instructions
conflict with the existing laws and regulations.
Whenever
such is the case, the legal requirements must control
and the instructions should be modified accordingly.
