For the 2004 Volvo XC90, low-beam fitment depends on the headlight type: models with halogen headlights use an H11 bulb, while models with HID headlights use a D2R bulb. The supplied fitment data does not list a high-beam bulb for this model year, so confirm the original bulb before ordering.
Front fog-light fitment is listed as H1 or 64136. Other notable exterior bulbs include 7507 for the rear turn signals, 7506 for the reverse lights, and 7506R for the brake lights. The center stop light uses an integrated LED assembly.
Several smaller exterior and interior applications share alternate listings. Parking, license-plate, front and rear side-marker, and courtesy lights use 2825 or 98. Dome and map lights use 6411 or 6428, while the step and trunk lights use 6418. Verify the vehicle’s existing bulb and lighting configuration where multiple options are shown.
