Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base.<
You can obtain a selection of replacement bulbs
at your BMW center.
Only change bulbs while they are cool to
the touch; otherwise, you could suffer
burns.<
When working on electrical systems,
always begin by switching off the con-
sumer in question; otherwise, short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<

Replacing components
148 For care of the headlamps, please follow the
instructions in the chapter entitled 'Care'.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours; otherwise, this could cause
irritation of the retina.<
Xenon lamps
These bulbs have a very long service life and are
highly unlikely to fail. If a xenon lamp fails never-
theless, switch on the fog lamps and continue
the journey with great care, provided that local
legislation does not prohibit this.
Have any work on the xenon lamp system,
including bulb replacements, performed
o n ly b y a BM W c e n t e r o r a w o r k s h o p t h a t w o r k s
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<
