Frequently Asked Questions

How do I know if my Volvo XC90 headlight assembly needs replacement?

If your XC90 headlight is completely dark, very dim compared to the other side, or has internal moisture and fogging that does not clear when the vehicle warms up, the assembly likely needs replacement. Dim output may also indicate a failing bulb, but if the bulb is new or recently replaced and the problem persists, the assembly itself is the culprit. A visual inspection of the lens for cracks or heavy yellowing will also confirm the need for service.

Do I need to replace both headlights at the same time?

Although this assembly is sold individually, replacing both the left and right headlights together is recommended for several reasons. Both assemblies age at the same rate, and replacing only one can result in noticeably different light output and color temperature between sides, affecting visibility and vehicle appearance. A complete front lighting refresh also ensures balanced illumination for safe nighttime driving.

What tools and skills are required to install this headlight assembly on my 2003–2014 XC90?

Installation typically requires basic hand tools, a socket set, and a screwdriver. You will need to access the assembly from inside the engine bay, remove fasteners, and disconnect the electrical connector. Consult your service manual for the exact location of mounting bolts and connector type for your model year. If you are not comfortable working with electrical connectors or engine bay components, professional installation is recommended to avoid damaging surrounding components or the assembly itself.

Is this a Genuine Volvo part or an aftermarket equivalent?

The Valeo 46973 is an OEM-equivalent replacement manufactured by Valeo, a leading supplier of lighting components to Volvo. It meets factory specifications for optical performance and durability. While not stamped with the Volvo logo, it is the same quality level used by dealerships for replacement service and is often more affordable than dealership-branded parts.

Will this headlight assembly fit my 2003 XC90 with the base engine?

Yes, the Valeo 46973 fits all 2003 XC90 models regardless of engine choice, including the base 2.5-liter naturally aspirated five-cylinder and the optional T6 turbocharged six-cylinder. The headlight assembly is the same across all 2003 XC90 variants. Always verify your specific model year and trim using the vehicle selector tool to confirm fitment before ordering.

Can I replace just the bulb instead of the entire headlight assembly?

If your headlight is dim or non-functional but the lens is clear and undamaged, try replacing the bulb first, as this is a much less expensive solution. However, if the lens is cracked, severely yellowed, or fogged with internal moisture, or if the bulb replacement does not restore proper brightness, the entire assembly must be replaced. Some XC90 model years have sealed assemblies where the bulb cannot be easily replaced without removing the entire unit.
