HID Headlamp Usage and Safety Precautions
| Special tools and workshop equipment
required |
| |
Note the following if working with HID headlamps: |
| Notes on hazardous high voltage/currents. Refer to
|
| Notes on pressure, temperature and radiation/electric arc.
Refer to
|
| Assembly instructions for HID headlamp bulbs. Refer to
|
| Disposal regulations for HID headlamp bulbs. Refer to
|
WARNING
| Always make sure to disconnect the battery ground
cable before performing work on parts of the headlamp
with a gas discharge lamp marked with yellow high
voltage symbols. |
| Then switch the low beams on and back off. This
removes any possible residual voltage. |
| The gas discharge lamp control module should not be
operated without the gas-discharge lamp. |
| Due to the high voltage (over 28000 V when igniting
the lamp), the gas-discharge lamp should only be
operated inside the headlamp housing. |
|
WARNING
| Never replace bulbs if you are not familiar with the
procedures, safety precautions and tools. |
|
| Notes on Hazardous High
Voltage/Currents |
WARNING
| 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. |
|
WARNING
| Turn off the ignition and all electric consumers and
remove the 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 |
WARNING
| 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 the HID lamp is approximately 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. |
|
WARNING
| 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 Headlamp Bulbs |
Caution
| Before replacing a bulb, the corresponding consumer
must always be switched off. |
| Turn off the ignition and all electric consumers and
remove the 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
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
Headlamp Bulbs |
WARNING
| HID lamps must be disposed of as hazardous waste,
never dispose of HID lamps via domestic waste. |
| HID 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. |
