Follow the instructions to change the affected bulb . Always use identical bulbs with the same designation. The designation is inscribed on the bulb, either on the glass part or on the base.

Do not touch the glass part of the bulb with unprotected fingers. The heat of the bulb would cause the fingerprint to evaporate and condense on the reflector. This will impair the brightness of the headlight.

After changing the bulb check to make sure that the bulb is working properly. If the bulb is not working properly, the bulb may not have been inserted properly or may have failed again, or the connector may have been inserted incorrectly.

Any time you change a bulb in the front of the vehicle, the headlight settings should be checked by a qualified workshop.
