The Mercedes-Benz ML63 AMG uses D1S, H7, and D2S bulb sizes for high and low beam headlight applications. The replacement chart contains specifications covering 2007 to 2015 model years.
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 most frequently specified type across the Mercedes-Benz ML63 AMG headlight data, appearing in both high beam and low beam positions across the 2007-2015 model years. It is a single-filament halogen bulb rated at 12V and 55W, fitted with a PX26d base, and carries ECE approval for use in Europe, the US, and Japan.
The D1S is the second most common bulb type in these specifications, used in both high beam and low beam HID headlamp configurations from 2007-2015, with the exception of the 2007 low beam position. It is an HID xenon discharge bulb rated at 85V and 35W, featuring a PK32d-2 base with an integral ignitor built into the bulb itself, designed exclusively for projector-type housings.
The D2S bulb appears only in the 2007 low beam position under HID headlamp fitment. Like the D1S, it is an 85V, 35W xenon discharge bulb for projector-type housings, but it uses a P32d-2 base and requires a separate external ignitor rather than a built-in one. This distinction makes D1S and D2S bulbs physically and electrically incompatible with each other despite sharing the same wattage rating.
For the Mercedes-Benz ML63 AMG, the high beam position on 2007-2011 models is specified exclusively as H7, with no HID option listed. From 2012-2015, the high beam position branches into either D1S or H7 depending on the headlamp system installed on the vehicle.
The low beam position carries a broader HID fitment range than the high beam, with D1S or D2S options listed alongside H7 from 2007 onward. This means the low beam housing type is a critical factor in determining the correct replacement bulb across all model years in the specifications.
Because the ML63 AMG is listed with two distinct bulb sizes for the same position and year in multiple instances, the headlamp system type installed on a specific vehicle must be confirmed before a replacement bulb is selected. Substituting an H7 halogen bulb into an HID projector housing, or vice versa, would represent an incompatible fitment.
The D1S and D2S bulbs share the same ECE standard classification and identical voltage and wattage ratings, but their base types differ. The PK32d-2 base of the D1S and the P32d-2 base of the D2S are not interchangeable, and the presence or absence of an integral ignitor further distinguishes the two types at the hardware level.
All three bulb types listed in the specifications, H7, D1S, and D2S, are manufactured to ECE standards, indicating they are designed for use in vehicles with headlamp systems that conform to European lighting regulations, which govern beam pattern and intensity output.
