Volvo XC90 Headlight Bulb Size

Additional Notes

• The H9 bulb is the high beam specification for the Volvo XC90 across the 2016-2021 model years in halogen capsule headlamp configurations, as well as in HID headlamp configurations from 2007-2012. The H9 is a halogen bulb operating at 65 watts with a PGJ19-5 base, and it is not directly interchangeable with the more common H11 or H7 types despite sharing a similar physical form factor.
• The H7 bulb appears as the high beam specification for halogen capsule headlamp configurations from 2003-2014, with the exception of 2015. It is a 55-watt halogen bulb with a PX26d base and is among the most widely used automotive halogen types globally.
• The D1S bulb is listed as both the high beam and low beam specification for HID headlamp configurations on the XC90 from 2007-2014. The D1S is a discharge bulb with an integrated igniter, operating at 35 watts and producing significantly higher luminous output than equivalent halogen types. Its integrated igniter design means it is not interchangeable with D2S or D3S bulbs.
• The D2R bulb is listed exclusively for low beam HID headlamp configurations on the 2003-2006 XC90. The D2R differs from the D2S in that it uses a shielded arc tube designed for projector-style reflector housings, and substituting a D2S in a D2R application can cause excessive glare for oncoming traffic.
• The H11 bulb serves as the low beam specification across halogen capsule headlamp configurations from 2003-2021. It operates at 55 watts with a PGJ19-2 base. Although the H11 and H9 share the same PGJ19 base family, their locking tab positions differ, making them non-interchangeable without modification.
• For the 2012-2014 XC90, three distinct bulb types are listed for the low beam position alone, specifically H7, H11, and D1S, reflecting the presence of multiple headlamp system variants within the same model year. Selecting the correct replacement requires confirming which headlamp system is installed on the specific vehicle.
• The 2006-2014 XC90 high beam configurations show a transition from H7 in halogen systems to D1S in HID systems, while the low beam HID specification shifted from D2R (2003-2006) to D1S (2007-2014). These two HID bulb types use different base designs and are not interchangeable with each other.
• From 2016 onward, the halogen capsule high beam specification consolidates solely to H9, with no HID high beam variant listed for those years, contrasting with earlier model years where HID and halogen high beam options coexisted.
