6 inches (152 mm) from a vertical
test screen or wall. The centerline of
the vehicle must be at a 90° angle to
the test screen.
2. Using a "T" square and a carpenter's
level, align and mark a vertical
centerline (8) on the test screen using
the outer reference point (low beam)
as found on each headlamp lens.
As a check, the distance between
centerlines should be 49
