Each lamp is aligned individually by
masking the other lamp. Head lamp
is first adjusted for proper height of
dipped beam by adjusting screw at
top. Light from dipped beam should
fall below horizontal and inclined
lines. No light should fall above these
lines. i.e., in “ The Dark Zone”.
Thereafter lateral adjustment is done
by adjusting screw at bottom so that
contour of dipped beam coincides
with the contour formed by
horizontal and inclined lines below
“Dark Zone”. When properly aligned,
most brightly illuminated area will be
just below the intersection A) of two
lines.
Head lamp on other side is adjusted
in a similar manner without
disturbing the position of vehicle and
screen. Now switch “ON” main beam
lights. They will be symmetrical above
points of intersection (point A & B)
of vertical lines and horizontal line.
It is possible that main beams may
not be exactly symmetrical but for
this reason head lamps should not be
realigned.
PREFERABLY, ALIGNMENT
SHOULD BE DONE IN THE DARK
Caution :
No masking of head lamps with black
paint is required. If done this will
reduce head lamp intensity.
