In 2007 Volvo started offering what they called "Active gas Discharge" headlamps. What they mean by "active" is that the headlamps can pivot with the steering to allow you to better see around corners.
The "active" gas discharge (xenon) headlamps use different bulbs than the regular gas discharge lamps. You may also see earlier models using these D2R bulbs in a non active headlamp housing (The bulbs do not turn in the housings) and a visual inspection will be needed for these models as well.
This bulb fits all P2 S60R & V70R models
