Main Headlamps With Gas-Discharge Lamps

Adjusting Headlamps

- Adjust headlamp with HID bulbs.

Notes On Application And Safety Instructions For Gas Discharge Lamps

CAUTION: Never replace lamps when you are not familiar with the corresponding actions, safety precautions and tools.

- If repair work is performed on main headlamp with gas discharge lamps, note the following:
- Notes on hazardous high voltage / currents
- Notes on pressure, temperature and radiation / electric arc
- Assembly notes for gas discharge lamps
- Disposal regulations for gas discharge lamps

Special tools, testers and auxiliary items required
- Protective eye wear
- Gloves

Notes on hazardous high voltage / currents

CAUTION:
- Control modules of lighting system, connectors or components in area of lamp socket carry hazardous high voltage.
- Operating the control module and igniter is only permissible with lamp.
- Switch off ignition, switch off all electrical components and remove ignition key.
- Make sure all components have zero potential when working on headlamp system, even residual voltage after switching off headlamps must be discharged.
- Residual voltages are discharged by switching low beam on and off again after ignition key was removed.
- Make sure lamps cannot be switched on when working on headlamp system.

Notes on pressure, temperature and radiation / glare

CAUTION:
- Lamp must only be operated in headlamp housing (protection against contact because of hot lamp, absorption of ultraviolet radiation, avoiding danger of glare, explosion protection).
- Glass cones of bulbs can become very hot - danger of burns
- Avoid looking directly into light beam, since UV radiation of gas discharge lamp is approx. 2.5 times higher than that of standard Halogen lamps.
- Avoid looking into light beam (danger of glare); vision can be impaired for a longer period of time.
- Avoid contact with burst glass cone.
- H7 bulbs and gas discharge lamps (Xenon / Bi-Xenon) are under pressure and can burst when replaced - danger of injury
- When removing and installing HID bulbs, always wear safety glasses and gloves.

Assembly notes on gas discharge lamps

CAUTION:
- Before replacing a bulb, the corresponding consumer must always be switched off.
- Switch off ignition, switch off all electrical components and remove ignition key.
- Do not touch glass cone of bulb with bare fingers, use clean cloth gloves. The remaining fingerprint would evaporate due to the heat of the operated bulb and would condense on the reflector which would impair headlamp luminosity.
- A bulb must only be replaced with one of the same version. Bulb identification can be found on bulb socket or glass cone.
- Harness connectors must engage correctly when installed and must be checked for proper connection.

Disposal regulations for gas discharge lamps

CAUTION:
- Gas discharge lamps must be disposed of as hazardous waste, never dispose of gas discharge lamps via domestic waste.
- Gas discharge lamps contain metallic mercury (Hg) and traces of thallium, they must not be destroyed.
- These components must be returned for proper recycling in accordance with national legislation.
- Dispose of only in the designated containers at the responsible collection point.
