HID Headlamps, Usage and Safety Precautions

Special tools, testers and auxiliary items required

• Protective Eyewear

• Gloves


• Never change bulbs if you are not familiar with the corresponding steps, safety precautions and the tool.

Always read the following instructions and precautions when assembling the HID headlamp

• Notes on hazardous high voltage / currents.

• Notes on pressure/temperature/radiation/electric arc.

• Assembly notes for HID lamps.

• Disposal regulations for HID lamps.

Notes On Hazardous High Voltage / Currents


Light system control modules, connectors or components in the bulb socket area conduct dangerous high voltage.

Control module and igniter operation is only permitted with lamp.


• Switch off the ignition and all electrical consumers and remove the ignition key.

• When working on headlamp system, ensure all components are without voltage, including relieving residual voltage after switching headlamps off.

• 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/Radiation/Electric Arc


• There are pressures from 7 bar (cold) to 100 bar (hot) in the glass portion of the HID bulb. Temperatures up to 700° C (1292 °F) are reached on the hot glass bulb.

• The glass can explode and there is a danger of burning.

• When removing and installing HID bulbs, always wear safety glasses and gloves.


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

• Do not look into the beam of light (danger of glare). It may interfere with the ability to see for a significant period of time.


• Avoid contact with burst glass cone.

• H7 bulbs and HID bulbs (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 HID Lamps


• Switch off the ignition and all electrical consumers and remove the ignition key.

• Do not touch the glass bulb with bare hands, use clean gloves. The remaining fingerprint would evaporate due to the heat of the operated bulb and 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 HID Lamps


• HID lamps must be disposed of as hazardous waste, never dispose of HID lamps via domestic waste.

• HID headlamp bulbs contain metallic mercury (Hg) and traces of thallium. Do not destroy the HID headlamp bulbs.

• 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.
