Installing:
Installation is carried out in the reverse order. When installing observe the following:
WARNING
Do not touch bulb glass when installing a bulb. Fingers leave traces of grease on the glass, which evaporate when the gas discharge bulb is switched on and cause the glass to cloud over.
Do not expose glass of gas discharge bulb to mechanical stress of any kind. The glass bulb is extremely sensitive and is also under a high internal pressure.
Avoid looking directly into the collimated beam as the UV radiation from the gas discharge bulb is about 2.5 times higher than from normal halogen bulbs.
Insert new gas discharge bulb so that locking lugs are positioned in recesses on reflector.
Connect connector and engage it.
Caution
When installing, make sure cover cap is correctly seated. The ingress of water will lead to permanent damage to the headlight.
Fit cover on headlight housing.
