The Mercedes-Benz E430 high beam headlight bulb uses H7 size, while low beam headlight bulbs use H7 or D2R sizes depending on configuration. The replacement chart covers vehicle production years spanning 1998 to 2002 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 the sole specified size for the high beam headlight on the Mercedes-Benz E430 across all model years from 1998-2002.
The H7 is a single-filament halogen bulb operating at 12V and 55W, fitted with a PX26d base and rated under ECE standards with approval also recognized in the US and Japan.
Low beam headlight fitment on the E430 across 1998-2002 depends on the headlamp system installed at the factory, with halogen capsule headlamps taking an H7 bulb and HID headlamps taking a D2R bulb.
The D2R is a high-intensity discharge xenon bulb rated at 85V and 35W, fitted with a P32d-3 base and designed specifically for reflector-type housings.
Unlike the H7, the D2R requires an external ignitor to initiate and sustain the electrical arc that produces light, making it incompatible with standard halogen wiring without additional components.
The reflector-specific designation of the D2R means it is not interchangeable with the D2S variant, which is intended for projector-type housings, even though both are HID xenon bulbs sharing the same wattage and voltage rating.
Because the high beam position uses only the H7 across all listed years while the low beam position accommodates two distinct bulb types, the headlamp system installed on a given vehicle must be confirmed before selecting a low beam replacement.
