Additional Notes

The H7 bulb is a single-filament halogen type rated at 12V and 55W, using a PX26d base. It carries ECE approval for use in Europe and worldwide markets, and is also approved for use in the United States and Japan.
The D1S and D2S bulbs are both HID (xenon) discharge types rated at 85V and 35W, designed for projector-type housings. Both follow the ECE standard applicable in Europe and worldwide markets.
A key distinction between D1S and D2S concerns ignition hardware. The D1S uses a PK32d-2 base and incorporates an integral ignitor within the bulb itself, while the D2S uses a P32d-2 base and requires a separate external ignitor in the housing.
On the Mercedes-Benz SLK55 AMG, the headlamp system type determines bulb fitment. Vehicles equipped with HID headlamps and those equipped with halogen capsule headlamps require entirely different bulb types, and the two are not interchangeable.
For model years 2012-2016, both high beam and low beam positions accept either D1S or H7, depending solely on whether the vehicle has HID or halogen headlamps. This dual-option fitment applies consistently across both positions for those years.
For model years 2005-2010, the low beam position on HID-equipped vehicles uses the D2S bulb rather than the D1S. This represents a direct fitment difference from the 2012-2016 HID specification, as D1S and D2S have different bases and ignitor configurations and are not interchangeable with each other.
For model years 2005-2010, the high beam position on all vehicles uses the H7 bulb exclusively, with no HID option listed for that position, unlike the low beam which offers both H7 and D2S depending on headlamp type.
