Volvo C30 Headlight Bulb Size

Additional Notes

• The Volvo C30 headlight system uses six distinct bulb types across its production run: H7, 9005, H9, D3S, H11, and D2S. Three of these are halogen types operating at 12V, while the remaining three are high-intensity discharge types requiring significantly higher operating voltages.
• The 9005 bulb is an ANSI-standard single-filament halogen type rated at 12V and 65W with a P20d base. It serves as the high beam bulb in the Volvo C30 for 2008-2009 across all headlamp configurations, and continues as an option in 2010-2013 on non-adaptive halogen and non-HID trims.
• The H7 bulb is an ECE-standard single-filament halogen type rated at 12V and 55W with a PX26d base. On the C30, it functions as the high beam bulb exclusively in the Adaptive HID headlamp configuration for 2010-2013, making it non-interchangeable with the 9005 despite both being single-filament 12V halogens, due to differing base designs.
• The H9 bulb is an ECE-standard single-filament halogen type rated at 12V and 65W with a PGJ19-5 base. It appears as the high beam bulb only in the standard HID headlamp configuration for 2010-2011, and its base type differs from both the H7 and 9005, meaning it is not a drop-in substitute for either.
• The D2S bulb is an ECE-standard HID discharge type rated at 85V and 35W with a P32d-2 base, designed for projector-type housings and requiring a separate external ignitor. It serves as the low beam bulb in the standard HID headlamp configuration across all C30 model years from 2008-2013.
• The D3S bulb is a mercury-free HID discharge type rated at 42V and 35W with a PK32d-5 base and an integrated ignitor, also designed for projector-type housings. It is used as the low beam bulb in the Adaptive HID headlamp configuration for 2010-2013. Despite sharing the same wattage as the D2S, the D3S and D2S are not interchangeable due to different base designs, voltage requirements, and ignitor configurations.
• The H11 bulb is an ECE-standard single-filament halogen type rated at 12V and 55W with a PGJ19-2 base. It functions as the low beam bulb in the Halogen Capsule headlamp configuration for all C30 model years from 2008-2013. Its PGJ19-2 base is physically distinct from the H7's PX26d base, and the two types are not interchangeable.
• The C30 headlamp system separates into three distinct configurations, each with its own specific bulb pairing: Halogen Capsule headlamps use 9005 high beam and H11 low beam; standard HID headlamps use H9 high beam and D2S low beam; and Adaptive HID headlamps use H7 high beam and D3S low beam. Substituting bulbs across configurations is not supported by the specifications, as each pairing corresponds to a different housing and electrical system design.
