Changing A Bulb; Front Lamps - CITROËN C4 Handbook

Changing a bulb
The headlamps are fitted with
polycarbonate glass with a protective
coating:
F do not clean them using a dry
or abrasive cloth, nor with a
detergent or solvent product,
F use a sponge and soapy water or a
pH neutral product,
F when using a high pressure washer
on persistent marks, do not keep
the lance directed towards the
lamps or their edges for too long,
so as not to damage their protective
coating and seals.
Changing a bulb should only be done
after the headlamp has been switched
off for several minutes (risk of serious
burns).
F Do not touch the bulb directly with
your fingers, use a lint-free cloth.
It is imperative to use only anti-
ultraviolet (UV) type bulbs to avoid
damaging the headlamp.
Always replace a failed bulb with a
new bulb with the same type and
specification.
