beam.
•Vehicle should have a normal trunk load.1. Park vehicle on level surface approximately 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.

Using a carpenter’s level, align and mark a vertical
centerline (1) on the test screen for each headlamp
lens at a distance of 25
3/4inches (654 mm) from
the vertical centerline. As a check, the distance
between centerlines should be 51
