The Mercedes-Benz S65 AMG uses H9 and H7 bulbs for high beam headlights, while low beam headlights require D1S, H7, or D2S bulbs depending on the specific size configuration. The replacement chart covers 2006 through 2013 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 H7 bulb is a single-filament halogen type operating at 12V and 55W, built to ECE standards and approved for use in the US and Japan. It uses a PX26d base and served as the high beam bulb in the Mercedes-Benz S65 AMG from 2006-2010.
The H9 bulb is a single-filament halogen type operating at 12V and 65W, built to ECE standards and approved for use in the US. It uses a PGJ19-5 base and replaced the H7 as the high beam bulb in the S65 AMG from 2011-2013. The H9 and H7 use different base types and are not interchangeable despite their similar voltage and general appearance.
The D1S is an HID (xenon) discharge bulb rated at 85V and 35W, designed specifically for projector-type headlight housings. It uses a PK32d-2 base and incorporates an integral ignitor, meaning no separate ignition component is required.
The D1S served as the low beam bulb across the S65 AMG from 2007-2013, making it the most consistently used bulb type across the listed specifications.
The D2S is also an HID (xenon) discharge bulb rated at 85V and 35W, designed for projector-type housings. Unlike the D1S, it uses a P32d-2 base and requires an external ignitor. These base and ignitor differences make D1S and D2S bulbs non-interchangeable.
The 2006 S65 AMG low beam position lists two separate bulb sizes: H7 for standard headlamp configurations and D2S for vehicles equipped with HID headlamps. This makes the 2006 model year the only one in the specifications where low beam fitment depends on the headlamp type installed.
The high beam position transitioned from H7 to H9 between the 2010 and 2011 model years. Both are halogen single-filament bulbs, but they carry different wattage ratings (55W versus 65W) and incompatible base fittings.
All four bulb types listed across these specifications conform to ECE standards, which govern bulb performance and safety requirements in Europe and internationally.
