Heavy Tactical Trucks…
here’s a procedure
for adjusting the
headlights of any
heavy tactical truck.
it’s guaranteed to aim the
headlight beam right where it
should—and get the glare out
of the eyes of other drivers.
before you do any
adjusting, though,
here’s a must: make
sure your vehicle
doesn’t have any
cargo in it.
otherwise, you’ll be
wasting your time.
you’ll get the right
adjustment only
when the vehicle’s
unloaded.
check and
adjust
headlights
following
these
steps…
1
Get a pencil
or chalk and a
measuring tape
or yardstick
for marking and
measuring.
2
Make sure your
truck’s tires have
the right amount
of air in them.
3
Clean your
truck’s headlights
and make sure
you can get to
the aiming screws.
That should
help you make
the necessary
adjustments.
4
Find some level terrain. if there’s pavement
in the area, that’s fine. Somewhere on the level
stretch, you’ll need a flat, vertical, light-colored
surface—a wall or fence—anything that’s straight up
and down. And you’ll need a level area extending
back from the vertical surface about
7
5 feet. That
should give you enough room to move your truck
back and forth as you check your headlights.
5
Now, using tape
measure or a
yardstick, mark a
line at right angles
to the wall and
bring it out 25 feet
from the wall.
6
Drive your vehicle up to the top of
the “T” so the headlights straddle the
25-foot line and are directly over the
straight line on top of the “T”.
Then at the 25-
foot mark, draw
a straight line
parallel to the
wall. Your work of
art should form
an oversized “T”.
Measure the distance
from the center of
the headlight to the
ground.
Mark off that same distance on the wall,
from the ground up, and draw a horizontal
line through that point, directly in front
of the vehicle. Call that line X.
