Additional Notes

The H7 bulb is a single-filament halogen type operating at 12V and 55W, fitted with a PX26d base. It carries ECE certification for use in Europe and worldwide markets, with additional approval in the United States and Japan.
The Mercedes-Benz C32 AMG uses the H7 bulb across all three model years (2002-2004) for the high beam headlight position, making it a consistent fitment throughout the entire production run covered by these specifications.
The low beam headlight position on the C32 AMG accommodates two distinct headlamp systems depending on the installed hardware: halogen capsule headlamps use the H7 bulb, while HID headlamps require a discharge bulb.
D2S and D2R are both HID (xenon) discharge bulbs sharing the same 85V, 35W electrical rating, yet they are not interchangeable. The D2S carries a P32d-2 base and is designed for projector-type housings, while the D2R carries a P32d-3 base and is intended for reflector-type housings.
Both D2S and D2R bulbs require an external ignitor to initiate the high-voltage arc necessary for operation, which distinguishes them from the self-contained H7 halogen bulb.
The 2002 C32 AMG with HID headlamps specifies the D2R bulb for the low beam position, whereas the 2003-2004 model years with HID headlamps specify the D2S bulb instead, indicating a housing type difference between the 2002 and later configurations.
