Replacing Exhausted Xenon Front Headlight Bulb

Model: Lancia Thesis MK 1 - Years 2002-2009
Part: Xenon headlight kit

Open the bonnet and remove the front headlight until it is completely detached, placing it on a work surface. To access the bulb, remove the plastic cover by unscrewing the retaining screw, then extract the bulb holder. Once the bulb holder is removed, take out the old exhausted bulb and insert the new xenon bulb, being very careful not to touch the glass bulb with your hands. Reposition the bulb holder in its housing and secure it with the spring. Refit the cover. Repeat the same operation with the other headlight. Check the operation by turning on the headlights.
