Bulbs can get hot during operation. Con‐
tact with the bulbs can cause burns. There is a
risk of injuries. Only change bulbs after they

can cause short circuits. There is a risk of inju‐
ries or a risk of property damage. When work‐
ing on the lighting system, switch off the lamps
in question. If necessary, heed the bulb manu‐
facturer's instructions.◀
DANGER
There can be high voltage in the lighting
system. There is danger to life. The manufac‐
turer of your vehicle recommends that the

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.

ternal lights in cool or humid weather. When
driving with the lights switched on, the con‐
densation evaporates after a short time. The
headlight glass does not need to be changed.
If despite driving with the lights switched on,
increasing humidity forms, e. g. water droplets
in the lamp, the manufacturer of your vehicle
recommends having it checked by a dealer’sSeite 229Replacing componentsMobility229
