! The headlamps are fitted with polycarbonate lenses coated with a protective varnish:

  • do not clean them with a dry or abrasive cloth, nor with a detergent or solvent product,
  • use a sponge and soapy water,
  • when using high-pressure washing on stubborn dirt, do not concentrate on the light units, the lights and their surrounds, to avoid damaging their coating and sealing gasket.
  • Do not touch the bulb directly with your fingers, use lint-free cloths.

Replace a bulb only when the light unit has been switched off for several minutes (risk of serious burns).

It is essential to use only anti-ultraviolet (UV) type bulbs, so as not to damage the light unit.

Always replace a faulty bulb with a new bulb of the same reference and specification.
