Many composite headlights do not have a
distinct “high intensity zone”. When
adjusting these lights you must locate the
area in the beam pattern that rises above
the rest of the beam. This part of the pattern
shines farthest down the road and is
considered the “high intensity zone”.
Many late model headlights have patterns
similar to the European beam pattern. You
should set these headlights using the
biased line as shown.
Some patterns do not have a distinct edge
on the right side. When aiming this type of
headlight, ignore the right side of the
pattern. Simply locate the left edge of the
high intensity area that shines farthest
down the road. This should be adjusted to
the centerline on the aiming screen. The
top edge will normally be easy to locate.

There are many different beam patterns used in domestic vehicles. When checking
headlights with complicated beam patterns, you must locate the part of the high intensity
zone that shines farthest down the road (
. This generally appears
as a “hump” in the beam pattern. Once this is located, you simply set the left edge of the
“hump” to align with the center cross hair on the screen. You set the top of the “hump”
with the horizontal cross hair. The bottom of the “hump” typically blends into the lower
portion of the beam pattern and is not considered when adjusting the headlight.
