Mercedes-Benz S430 Headlight Bulb Size

The Mercedes-Benz S430 high beam headlight uses an H7 bulb size, while low beam headlight applications utilize H7, D2S, or D2R bulb sizes depending on the specific vehicle configuration. The replacement chart covers 2000 to 2006 model years with corresponding bulb size specifications for each production year.

Additional Notes

The H7 bulb is a single-filament halogen type rated at 12V and 55W, fitted with a PX26d base. It serves as the high beam headlight bulb across all model years of the Mercedes-Benz S430 from 2000-2006.
The H7 bulb also functions as the low beam headlight on S430 units not equipped with HID headlamps, covering the same 2000-2006 span in that role.
Two distinct HID bulb types appear in the low beam specifications depending on model year. The D2R was listed for 2000-2002, while the D2S replaced it for 2003-2006.
The D2R and D2S are both high-intensity discharge xenon bulbs rated at 85V and 35W. Despite sharing the same wattage and voltage, they are not interchangeable, as the D2R carries a P32d-3 base intended for reflector-type housings, while the D2S uses a P32d-2 base designed for projector-type housings.
Both the D2R and D2S require an external ignitor to initiate the electrical arc that produces light, unlike the H7, which operates directly from the vehicle's standard 12V circuit.
The HID low beam options on the S430 are listed as conditional fitments, applying only to vehicles equipped with HID headlamps. Units without that equipment use the H7 halogen bulb in the low beam position instead.
All three bulb types, H7, D2S, and D2R, conform to ECE standards and carry approval for use in Europe and worldwide markets. The H7 additionally holds approval in the United States and Japan.
