Installing

Install in reverse order of removal. Note the following:

• Do not touch the glass of the HID bulb when installing. Your fingers will leave traces of grease on the glass which will evaporate and cloud the glass when the bulb is switched on.

• Do not subject the HID bulb glass to any mechanical stress. Glass cone is extremely sensitive and is also under high pressure.

• Avoid looking directly into the light beam, since the UV rays given off by the HID bulb are approximately 2.5 times stronger than those of a halogen bulb.

• Make sure seal has proper seating when installing bracket with headlamp power output stage. It is destroyed by ingress of water into headlamp.

• If a headlamp with automatic vertical headlamp aim control is removed, basic setting of headlamps must always be performed after installation. Refer to => Maintenance Procedures.

- Insert new HID lamp so that retaining tabs lie in cut-outs in reflector.

- Check headlamp for function.

- Check headlamp adjustment and adjust headlamp if necessary.
