How to Change a Headlight in a Volvo XC90

Volvo offers its XC90 crossover with two optional headlight systems. One is a halogen bulb in a composite headlight assembly and the second is a Bi-Xenon system. The Bi-Xenon system is not serviceable at home due to the high-voltage electricity used by the system. Replacing the headlights in this car requires the removal of the headlight assembly to access the bulbs. You can get the halogen bulbs for your XC90 from any auto part store or through your Volvo dealer.

Turn the headlight switch off and be sure the ignition key is off before working on the headlights. Open the bonnet of the car and locate the headlight assembly.

Locate the two locking pins at top of the headlight assembly. There is one on each side of the assembly along the back edge. Grasp the rods and pull them straight up.

Lift the headlight assembly out of the car and disconnect the electrical connector from the assembly. Press the locking tab and carefully pull the connector out of the assembly.

Locate the outer cover on the rear of the headlight assembly. Pull it straight out of the assembly to access the bulb behind it. Unplug the connector from the back of the bulb, just inside the cover. Remove the bulb and discard it.

Install a new bulb into the housing, being careful not to touch the glass on the bulb. The oil on your hands will cause the bulb to overheat and shatter. Plug in the electrical connector and install the rear cover on the headlight assembly.

Plug the electrical connector into the bottom of the headlight assembly and slide the assembly back into the car. Push the locking pins down to secure the headlight assembly to the car. Repeat the process to change the halogen bulb in the opposite assembly.

Turn the headlight switch on to verify they are working properly.
