The Mercedes-Benz E55 AMG high beam headlight uses an H7 bulb size, while low beam headlights accommodate H7, D2S, or D2R bulb sizes. The replacement chart covers 1999 to 2006 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 H7 is a single-filament halogen bulb with a PX26d base, rated at 12V and 55W. It operates under ECE standards and holds approval for use in the US and Japan as well.
The Mercedes-Benz E55 AMG uses the H7 bulb exclusively for the high beam headlight across all model years from 1999-2006.
For the low beam headlight, the E55 AMG accommodates either halogen or HID (xenon) bulbs depending on the headlamp system fitted to the vehicle, making headlamp type verification necessary before purchasing a replacement bulb.
The D2S and D2R are both HID (xenon) discharge bulbs rated at 85V and 35W. Despite sharing the same wattage and voltage, they are not interchangeable, as the D2S carries a P32d-2 base intended for projector-type housings, while the D2R carries a P32d-3 base intended for reflector-type housings.
Both D2S and D2R bulbs require an external ignitor to initiate the high-voltage arc that produces light, unlike the H7, which operates directly from the vehicle's 12V electrical system.
On 1999-2002 E55 AMG models equipped with HID headlamps, the low beam bulb is the D2R, which is specific to reflector-type housings. From 2003-2006, HID-equipped vehicles use the D2S instead, indicating a change in headlamp housing design between those production periods.
On 1999-2002 models with halogen headlamps, the low beam specification explicitly notes "Halogen Capsule Headlamps," while 2003-2006 halogen low beam entries list H7 without that qualifier, though both use the same H7 bulb.
