Operation and safety notes for gas

discharge bulbs

– If repairs are to be made to the headlight with gas discharge

bulbs, observe the following:

♦ Notes on dangerous high voltage/currents ⇒ page 68

♦ Notes on pressure, temperature, radiation/arcs ⇒ page 69

♦ Assembly notes for gas discharge bulbs ⇒ page 70

♦ Disposal regulations for gas discharge bulbs ⇒ page 70

Special tools and workshop equipment required

♦ Protective goggles

♦ Gloves

WARNING

It is absolutely necessary to disconnect the battery earth strap

before working on parts of the gas discharge headlights

marked with yellow high voltage symbols.

Then switch dipped beam on and off again. This will eliminate

any possible residual voltage.

The gas discharge lamp control unit must never be operated

without a gas discharge lamp.

Due to the high voltage (above 28000 V when igniting the gas

discharge bulb) and temperatures, the gas discharge bulb

must only be operated in the headlight housing.

WARNING

♦ Never change bulbs if you are not familiar with the appro‐

priate procedures, safety precautions and tools.

Notes on dangerous high voltage and current

WARNING

Control units for light systems, connectors and components

pertaining to bulb holders conduct lethally high voltage.

Operating the control unit and the starter unit is permitted only

with the bulb fitted.

WARNING

•

Switch off ignition and all electrical consumers and re‐

move ignition key.

When working on headlight system, ensure that there is

no voltage in any components, including the dissipation of

residual voltage after the headlights are switched off.

•

Residual voltage can be dissipated by turning the dipped

beams on and then off again after withdrawing the ignition

key.

When working on the headlight system, ensure that the

lights cannot be switched on.

Notes on pressure, temperature, radiation/arcs

WARNING

•

The bulbs may be operated in the headlight housing only

(protection against contact due to very hot bulbs, absorp‐

tion of UV radiation, avoidance of dazzling light, protection

against explosion).

•

The glass of the bulbs can be very hot - danger of burns.

Avoid looking directly into the beam, as the UV rays from

the gas discharge bulb are about 2.5 times greater than

normal halogen bulbs.

•

Avoid looking into the light beam (danger of glare); vision

may be impaired for a substantial time.

WARNING

•

Avoid contact with burst bulbs.

H7 bulbs and gas discharge bulbs (xenon and bi-xenon)

are under pressure and can explode while being changed

- danger of injury.

•

Always wear protective goggles and gloves when remov‐

ing and installing gas discharge bulbs.

Repair notes for gas discharge bulbs

Caution

♦ Before exchanging a bulb, always switch off the affected

lk

consumers.

♦ Switch off ignition and all electrical consumers and re‐

move ignition key.

♦ Do not touch the bulb glass with bare fingers; use clean

cloth gloves. When the light bulb is switched on, the heat

would vaporise the oil of the finger prints which would then

settle on the reflector, impairing the brightness of the

headlight.

♦ A light bulb must always be renewed with a bulb of the

same sort. The designation appears on the base of the

bulb or on the bulb glass.

♦ Properly engage connectors during installation and en‐

sure tight seating of the connection.

Disposal regulations for gas discharge bulbs

WARNING

•

Gas discharge bulbs must be disposed of as hazardous

waste; never dispose of gas discharge bulbs as conven‐

tional waste.

•

Gas discharge bulbs contain metallic mercury (Hg) and

traces of thallium; never destroy these bulbs.

These components must be recycled in accordance with

national law.

Dispose of only in containers intended for this purpose at

an authorised collection point.
