Mercedes-Benz CLS63 AMG Headlight Bulb Size

The Mercedes-Benz CLS63 AMG uses D1S, H7, and D2S bulb sizes for high and low beam headlight applications, with specific configurations varying by model year. The replacement chart covers 2007 to 2014 production years and details the corresponding bulb size specifications for each headlight beam type.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The H7 bulb is a single-filament halogen type rated at 12V and 55W, operating on a PX26d base. It carries ECE approval for use across Europe and worldwide, and is also approved for use in the United States and Japan.
The D1S and D2S bulbs are both HID (xenon) gas-discharge types rated at 85V and 35W, designed for projector-type housings. Both follow the ECE standard applicable in Europe and worldwide.
The primary distinction between D1S and D2S lies in their ignition systems. 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.
On the Mercedes-Benz CLS63 AMG, the 2012-2014 model years use D1S bulbs for both high beam and low beam positions when equipped with HID headlamps.
For the 2007-2011 model years, the high beam position is served exclusively by the H7 halogen bulb, with no HID variant listed for that position.
The low beam position on 2007-2011 models presents two distinct fitments: H7 for halogen-equipped vehicles and D2S for those fitted with HID headlamps. These are not interchangeable, as each corresponds to a different headlamp system.
Because the D1S and D2S share the same wattage but differ in base type and ignitor configuration, the two bulbs are not interchangeable with each other despite their similar electrical ratings.
The shift from D2S on 2007-2011 HID low beam applications to D1S on 2012-2014 reflects a change in the ignitor architecture, moving from an external ignitor arrangement to one integrated directly into the bulb.
