HEADLIGHTS
GAS-DISCHARGE (BI-XENO)
MAIN BEAM / DIPPED BEAM
HEADLIGHTS AND DYNAMIC
BEAM ADJUSTMENT DEVICE
These headlights, called Bi-Xeno,
use a lamp with a xenon-filled bulb,
both for the dipped beam and the
main beam headlights.
The main characteristics of this
type of headlights are:
– higher brilliancy
– higher light beam width and
adjustability
– lower consumption under work-
ing conditions
– longer bulb life.Each headlight is equipped with an
electronic control unit used to con-
trol supply voltage. Due to high bril-
liancy, bi-Xeno headlights require
the adoption of a dynamic beam
adjustment control system.
This system is controlled by an
electronic control unit operating at
two levels:
– constant headlight beam realign-
ment as a function of the car load
– dynamic headlight beam align-
ment to compensate car pitching
when running.Operation
Light is projected onto the road by
means of a spherical glass lens with
a large surface (70 mm diameter).
A deflector lifts and lowers, so that
light distribution is different for
both the main beam and dipped
beam headlights. The deflector is
electrically operated and the
mechanical lifting/lowering opera-
tion is performed real-time when
lights are switched.
The xenon lamp consists of a bulb
containing low-pressure xenon and
two electrodes.
To obtain light emission, an elec-
tric arc must be triggered between
the two electrodes and maintained.
Each headlight is equipped with a
control unit which:
– checks the voltage/current value
under working operation
– triggers the arc to the electrodes
and cause salt evaporation at
switching on.

You should, where pos-
sible, have your bulbs
changed at a Lancia
Dealership. The correct operation
and slant of headlights is essen-
tial for safe driving and compli-
ance with legal requirements.IF A BULB BURNS
OUT
Modifications or repairs
to the electrical system
carried out incorrectly
and without bearing the features
of the system in mind can cause
malfunctions with the risk of fire.
The bulbs of (bi-Xeno)
gas-discharge headlights
must be replaced by a
Lancia Dealership.
Only touch the metal
part when handling halo-
gen bulbs. You will
reduce the light intensity and
possibly compromise bulb life by
touching the glass bulb. If you
touch the bulb accidentally, rub
it with a cloth moistened with
alcohol and leave it to dry.
Halogen bulbs contain
pressurised gas which, if
broken, may cause small
fragments of glass to be projected
outwards.
Due to high voltage, the
bulb of bi-Xeno gas-dis-
charge headlights must
only be replaced by experts: dan-
ger of death! Contact the Lancia
Dealership.

GENERAL INSTRUCTIONS
– When a light is not working,
check that it has not fused before
changing the bulb.
– For the location of the fuses, refer
to “If a fuse blows” in this chapter.
– Before replacing a bulb that does
not work, check that the contacts are
not oxidised.
– Burnt-out bulbs must be replaced
with ones of the same type and
power.
– Always check the slant of the
headlight beam after changing a
bulb for safety reasons.TYPES OF BULBS
Different types of bulbs are
installed in the car (fig. 22):
A - All glass bulbs
Snapped into position. Pull to
remove.
B - Bayonet connection bulbs
Remove from the bulb holder by
pressing the bulb and rotating it
anticlockwise.
C - Cylindrical bulbs
Remove by pulling away from ter-
minals.
D - E Halogen bulbs
To remove the bulb, release the
clip holding the bulb in place.

IF AN EXTERIOR
BULB BURNS OUT
FRONT LIGHT CLUSTER
The front light cluster includes
main beam headlights/dipped beam
headlights, additional main beam
headlights, direction indicators and
sidelights.Light layout is the following
(fig. 23):
A– Main beam headlight/dipped
beam headlight (bi-Xeno bulb)
B– Sidelight
C– Additional main beam head-
light
D– Direction indicator.Any operation on the
front light cluster must be
made with the stalk at 0
(lights off) and ignition key
removed for at least 15 minutes
(to let bulb cooling and con-
densers discharging): risk of elec-
trical discharge!
fig. 23
L0A0106b
To replace front head-
light bulbs, front light
clusters shall be removed.
It is therefore recommended to
the bulbs replaced at Lancia
Dealership.Due to high voltage, the
bulb of bi-Xeno gas-dis-
charge headlights must
only be replaced by experts: dan-
ger of death! Contact the Lancia
Dealership.
