5 Turn on the low beam headlights and
place a piece of cardboard or equivalent
(although not directly on the lens) in front
of the headlight not being aimed. This
should allow the beam cut-off of the
headlight being aimed to be seen on the
flat surface.
NOTICE
Do not cover a headlight directly on the
lens to improve beam cut-off when aim-
ing. Covering a headlight may cause
excessive heat build-up which may cause
damage to the headlight.
Correctly adjusted low beam
