Halogen bulbs must be handled holding the metal-
lic part only. Touching the transparent part of the
bulb with your fingers may reduce the intensity
of the light emitted and even compromise the longevity
of the bulb itself. In the event of accidental contact, wipe
the bulb with an alcohol-soaked cloth and leave to dry.
Modifications or repairs to the electrical system
(electronic control units) that are not carried out
properly or do not take the technical specifications
of the system into account can cause malfunctions lead-
ing to the risk of fire.
Halogen bulbs contain pressurised gas which may
cause small fragments of glass to be projected out-
wards if the bulb is broken.
Due to the high power supply voltage, gas dis-
charge bulbs (Bi-Xenon) should only be replaced
by specialised personnel: danger of death! Contact
Alfa Romeo Authorized Services.
IMPORTANT When the weather is cold or damp or after heavy rain
or after washing, the surface of headlights or rear lights, may steam
up and/or form drops of condensation on the inside. This is a nat-
ural phenomenon due to the difference in temperature and humidity
between the inside and the outside of the glass which does not
indicate a fault and does not compromise the normal operation of
lighting devices. The mist disappears quickly turning the lights on,
starting from the centre of the diffuser, extending progressively
towards the edges.
CHANGING A BULB
GENERAL INSTRUCTIONS
❍Before changing a bulb check the contacts for oxidation;
❍blown bulbs must be replaced with others of the same type
and power:
❍after replacing a headlight bulb, always check its alignment;
❍when a light is not working, check that the corresponding fuse
is intact before changing the bulb. For the location of fuses, re-
fer to the “Changing a fuse” paragraph in this section.
