The Volvo V50 high beam headlight uses 9005 and H7 bulb sizes, while low beam headlight applications require H11, D1S, or D2S bulb sizes. The replacement chart covers 2005 through 2011 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Volvo V50 high beam headlight uses either the 9005 or H7 bulb type depending on the headlamp system fitted. The 9005 is an ANSI-standard single-filament halogen bulb rated at 12V and 65W with a P20d base, while the H7 is an ECE-standard single-filament halogen bulb rated at 12V and 55W with a PX26d base. These two types are not interchangeable due to their differing base configurations and wattage ratings.
The low beam headlight on the Volvo V50 (2005-2011) uses the H11 halogen bulb in halogen capsule headlamp configurations across all model years covered. The H11 is an ECE-standard single-filament bulb with a PGJ19-2 base, rated at 12V and 55W.
For the 2008-2011 Volvo V50 fitted with HID headlamps, the low beam position uses the D1S bulb. The D1S is an ECE-standard xenon discharge bulb with a PK32d-2 base and an integral ignitor, designed specifically for projector-type housings, and operates at 85V and 35W.
The 2005-2007 V50 with HID headlamps uses the D2S bulb for the low beam position. Unlike the D1S, the D2S has a P32d-2 base and requires an external ignitor rather than an integrated one. Both D1S and D2S operate at 85V and 35W, but their base types and ignitor configurations make them incompatible with each other.
The high beam position on V50 models with HID low beam headlamps uses the H7 halogen bulb for 2008-2011. This pairing of a halogen high beam with a discharge low beam is a recognized configuration in projector-style HID headlamp systems.
For the 2005-2007 V50, the high beam headlight is listed solely with the 9005 bulb, with no HID variant noted for that position during those years.
The 9005 and H7 bulbs both serve the high beam position but follow different regulatory standards. The 9005 is governed by ANSI standards applicable in the US and Canada, whereas the H7 follows ECE standards used in Europe and worldwide, with additional approval in the US and Japan.
The D1S and D2S bulbs are both rated at 85V and 35W and are both intended for projector-type housings, but their base types differ. The D1S uses a PK32d-2 base with an integral ignitor, while the D2S uses a P32d-2 base and depends on an external ignitor, making the two types physically and electrically distinct.
