The Mercedes-Benz SLK32 AMG high beam headlight uses an H7 bulb size, while low beam headlights accommodate H7, D2S, or D2R bulb sizes. The replacement chart covers 2002 to 2004 model 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, fitted with a PX26d base. It holds ECE certification for use in Europe and worldwide markets, and is also approved for use in the United States and Japan.
The Mercedes-Benz SLK32 AMG uses the H7 bulb across all three model years (2002-2004) for the high beam headlight position, with no variation by year or trim.
The low beam headlight position on the SLK32 AMG is headlamp-system dependent, meaning the correct bulb type is determined by whether the vehicle is equipped with halogen capsule headlamps or HID headlamps.
Vehicles fitted with halogen capsule headlamps use the H7 bulb for low beam across all three years (2002-2004), consistent with the high beam specification.
The D2S and D2R are both HID xenon discharge bulbs operating at 85V and 35W. Despite sharing the same voltage and wattage, they are not interchangeable, as each is designed for a specific housing type and carries a different base configuration.
The D2S bulb uses a P32d-2 base and is intended for projector-type headlamp housings. The D2R uses a P32d-3 base and is designed for reflector-type housings. Installing either bulb in the wrong housing type would result in an incorrect fitment.
Both D2S and D2R bulbs require an external ignitor to operate, as HID discharge technology does not function with a standard low-voltage circuit alone.
The 2004 model year specifies the D2S bulb for HID-equipped low beams, while the 2002-2003 model years specify the D2R for the same position, indicating a housing-type difference between these production periods.
