2012 FORD MUSTANG headlamp

•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line
2. Measure the height from the
center of your headlamp to the
ground and mark an 8 foot
(2.4 meter) horizontal reference line
on the vertical wall or screen at this
height (a piece of masking tape works well). The center of the lamp is
marked bya3mmcircleontheheadlamp lens.
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. To see a clearer light pattern for adjusting, block the
light from one headlamp while adjusting the other.
For vehicles with halogen headlamps:
On the wall or screen you will
observe a flat zone of high intensity
light located at the top of the right
hand portion of the beam pattern. If
the top edge of the high intensity
light zone is not at the horizontal
reference line, the headlamp will
need to be adjusted.
For vehicles with HID headlamps:
There is a distinct cut-off (change
from light to dark) in the left
portion of the beam pattern. The
top edge of this cut-off should be
positioned two inches (50.8 mm)
below the horizontal reference line.

and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.
