Notes on bulb replacement

Only use 12-volt bulbs of the same type
and with the specified watt rating.


Switch the lights off before changing a
bulb to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not

lamps replaced by an authorized
Mercedes-Benz Light Truck Center:


the additional turn signal lamps in the
exterior rear view mirrors
