The high voltage element of gas discharge lamps* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
•
When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.Caution

Please ask your specialist retailer how to dispose of used bulbs in the proper
manner.
Note
•
Depending on weather conditions (cold or wet), the front lights, the fog
lights, the rear lights and the indicato rs may be temporarily misted. This has
no influence on the life expectancy of the lighting system. By switching on the
lights, the area through which the beam of light is projected will quickly be
demisted. However, the edges may continue to be misted.

or paper towel instead. Otherwise, the fingerprints left on the glass will vaporise as a result of the heat generated by the bulb, be deposited on the
reflector and impair its surface.
