Changing a bulb
For bulbs that have alignment
lugs (H1, H7...) ensure that they are
fitted correctly for the best lighting
performance.
The headlamps have polycarbonate
lenses with a protective coating:
F

d

o not clean them using a dr y
or abrasive cloth, nor with a
detergent or solvent product,
F

u

se a sponge and soapy water,
F

w

hen 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.
F

D

o not touch the bulb directly with
your fingers, use lint-free cloths.
Changing a bulb should only be done
after the headlamp has been switched
