Never use a bulb which has been dropped.
Such a bulb may break or even explode and
injure you.
Halogenb ulbs are pressurised and can
explode when you change them, particularly
if they are very hot .You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 104). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correc ttype.
If the new bulb still does no tlight up, consult
a qualified specialist workshop.
