headlight bulb Alfa Romeo GT 2007 Owner handbook (in English)

Halogen bulbs must be
handled touching only the
metallic part. If the trans-
parent bulb is touched with the fin-
gers, its lighting intensity is re-
duced and life of the bulb may be
compromised. If touched acciden-
tally, rub the bulb with a cloth
moistened with alcohol and allow
to dry.
IN AN EMERGENCY
192
Halogen bulbs contain
pressurised gas which, if
broken, may cause small
fragments of glass to be project-
ed outwards.WHEN NEEDING TO
CHANGE A BULB
Alterations or repairs to
the electric system not car-
ried out correctly and with-
out taking into account the specifi-
cations of the system may cause
malfunctioning and the risk of fire.
Where possible the bulbs
should be replaced by Alfa
Romeo Authorized Ser-
vices. The correct operation and po-
sitioning of the external lights are
vital to the safety of the car and
its passengers and the subject of
specific laws.
Due to high voltage, the
bulb of (Xenon) gas-dis-
charge headlights must on-
ly be replaced by experts: danger
of death! Contact Alfa Romeo Au-
thorized Services.

IMPORTANTWhen needing to change
the left bulb, the side trim next to the light

cess to the engine compartment.

After replacement, refit
the covers correctly check-
ing that they are properly
secured.
IMPORTANTA slight layer of steam
(fogging) can appear on the inside surface
of the beam transparent cover: this is not
a defect. The presence of condensate traces
in beams is a natural phenomenon, due to
a low temperature and to the degree of hu-
midity in the air. These traces will disappear
when the beams are turned on. Drops of wa-
ter inside the headlight indicate instead wa-
ter infiltration: contact Alfa Romeo Autho-
rised Services.
