HEADLIGHT ADJUSTMENT
ABROAD
(
fig. 135
)
The dipped-beam headlights are adjusted
for circulation in the country in which the ve-
hicle is marketed. In countries with opposite
circulation, to avoid glaring oncoming vehi-
cles it is necessary to cover the areas of the
headlight as shown below; this is done us-
ing non-transparent sticker tape.
The illustration refers to passing from right-
hand drive to left-hand drive.
GAS DISCHARGE
HEADLIGHTS
(optional for versions/markets
where applicable)
The gas (xenon) discharge headlights op-
erate with a voltaic arc, in an ambient sat-
urated with pressure xenon, instead of the
glow filament.
The resulting illumination is sensibly high-
er to that of conventional lamps, both for
light quality (clearer light) and for the width
and positioning of the illuminated area.
The advantages of better illumination can
be perceived (due to less eyesight fatigue
and greater orientation capacity for the dri-
ver, which in turn means higher driving safe-
ty) especially in case of bad weather, fog
and/or insufficient road signs, thanks to the
better illumination of the side parts of the
visual field, normally obscured.
The large increase of the side part illumi-
nation increases driving safety since it allows
the driver to better see the other users on
the edge of the road (pedestrians, cyclists
and bikers).
The triggering of the voltaic arc requires a
very high voltage, while subsequent power
supply can take place at a low voltage.
The headlights achieve their top luminosi-
ty approx. 15 seconds after they are switched
on.
The intense light produced by this type of
headlights requires the use of an automat-
ic system to keep headlight trim constant
and avoid dazzling the vehicles coming from
the opposite direction in case of braking, ac-
celeration or when carrying loads.
The electric mechanical system for auto-
matically keeping the trim constant, makes
unnecessary the device for compensating
the headlight dip and the visual indication
of the position on the display.
Xenon lights have a very long life, there-
fore breakdowns are unlikely.
If necessary, have the sys-
tem checked and repaired
only by Alfa Romeo Authorized
Services.
