headlamp BMW M4 2015 Owners Manual

You can obtain a selection of replacement
bulbs at the service center.
Danger of burns
Only change bulbs when they are cool;
otherwise, there is a danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always reel off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement
on xenon headlights
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center. Due to the high voltage
present in the system, there is a danger of fatal
injuries if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, 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.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.
If the headlights do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the service center check this.
Headlight setting The headlight adjustments can be affected by
changing lights and bulbs. Have the head‐
lights' settings checked and corrected by serv‐
ice after a replacement.

Xenon headlights
Because of the long life of these bulbs, the
likelihood of failure is very low. Switching the
lights on and off frequently shortens their life.
Do not perform work/bulb replacement
on xenon headlights
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center. Due to the high voltage present in the system, there is a danger of fatal
injuries if work is carried out improperly.◀
