The Mercedes-Benz S63 AMG uses H9 and H7 bulbs for high beam headlight functions, while the low beam headlight requires a D1S bulb size. The replacement chart covers 2008 to 2013 model years with corresponding bulb size specifications for each production year.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz S63 AMG uses two distinct high beam bulb types across its model years: the H7 for 2008-2010 and the H9 for 2011-2013. These are not interchangeable, as they use different bases, the PX26d and PGJ19-5 respectively, and operate at different wattages.
The H7 is a single-filament halogen bulb rated at 12V and 55W, conforming to the ECE standard with approval also covering the US and Japan. Its PX26d base is among the most widely used in halogen headlight applications.
The H9 is likewise a single-filament halogen bulb operating at 12V but draws 65W, making it a higher-output type than the H7. It carries ECE approval and is also approved in the US, though its PGJ19-5 base is specific to the H9 and is not shared with the H7.
The low beam headlight position on the S63 AMG uses the D1S bulb across all listed years, 2008-2013, without variation.
The D1S is an HID (high-intensity discharge) xenon bulb rated at 85V and 35W. Unlike halogen types, it produces light through an electrical arc between tungsten electrodes within a xenon gas-filled quartz capsule rather than through a heated filament.
The D1S incorporates an integral ignitor within the bulb assembly itself, which distinguishes it from other HID types such as the D2S, where the ignitor is housed separately in the ballast. This integration affects physical fitment and means the D1S is not interchangeable with D2S or D3S bulbs despite similar operating principles.
The D1S uses a PK32d-2 base and is designed specifically for projector-type headlight housings, meaning it is not suited for reflector-type housings without modification to the optical system.
