Note

♦

Do not touch bulb glass when fitting a gas discharge lamp

bulb . Fingers leave traces of grease on the glass, which when

switching the gas discharge lamp bulb on, evaporate and

cause the glass to cloud over.

♦

Use extreme care when fitting a gas discharge lamp bulb and

do not subject the bulb to mechanical stress. The glass bulb

is extremely sensitive and is subjected to a very high pressure.

♦

Avoid looking directly into the collimated beam as the UV rays

from the gas discharge bulb are about 2.5 times greater than

normal halogen bulbs.

♦

When installing cap, ensure that it is seated correctly. The in‐

gress of water will lead to permanent damage of the headlight.

♦

If a headlight is removed with automatic range control, the ba‐

sic setting of the headlight should always be checked when

reinstalling ⇒ Maintenance ; Booklet  20.1 .

Installation is performed in the reverse order of installation; when

doing this, note the following:
– Check function of headlight.
– Check headlight setting and adjust headlight as necessary
