Volvo S80 Headlight Bulb Size

Additional Notes

• The H7 bulb is the most widely specified type across the Volvo S80 headlight data, appearing in both high beam and low beam positions across multiple model years and headlamp system types. It follows the ECE standard, carries a PX26d base, and operates at 12V and 55W with a single filament.
• The H9 bulb serves as the high beam source in halogen capsule headlamp systems on the Volvo S80 from 2007-2016. It shares the same 12V operating voltage as the H7 but draws 65W and uses a PGJ19-5 base, making it physically and electrically incompatible with H7 sockets despite the similar appearance of both types.
• The D1S bulb is specified for the low beam position in HID-equipped Volvo S80 models from 2007-2016. As a discharge bulb, it operates at 85V and 35W and incorporates an integral ignitor within the bulb body itself, distinguishing it from discharge types that rely on a separate external ignitor.
• The D2R bulb fills the low beam role in HID-equipped S80 models from 2004-2006. It also operates at 85V and 35W but uses a P32d-3 base and requires an external ignitor. The D2R is specifically designed for reflector-type housings, and its coating is formulated to prevent stray light scatter within that housing geometry, making it non-interchangeable with projector-type equivalents such as the D2S.
• The 9005 bulb is listed as the high beam source in HID-equipped S80 models from 2004-2006. Unlike the H-series bulbs in the same data set, the 9005 follows the ANSI standard used in the US and Canada rather than the ECE standard, and it uses a P20d base at 12V and 65W.
• The H11 bulb appears exclusively in the low beam position of halogen capsule headlamp systems on the S80 from 2007-2013. It operates at 12V and 55W with a PGJ19-2 base. Although its wattage matches the H7, the two types use different base configurations and are not interchangeable.
• The S80 with halogen capsule headlamps shifted its low beam specification from H7 to H11 between the 2006 and 2007 model years, then reverted to H7 between the 2013 and 2014 model years. These transitions indicate housing design changes that affect bulb fitment even within the same headlamp system category.
• In HID-equipped S80 models, the high beam and low beam positions use entirely different bulb technologies. The low beam relies on a discharge bulb (D1S or D2R depending on year), while the high beam uses a conventional halogen bulb (H7 for 2007-2016, 9005 for 2004-2006). The two discharge types are not interchangeable with each other due to differences in base design, ignitor configuration, and housing compatibility.
