The Mercedes-Benz SLS AMG uses D1S bulb size for both high beam and low beam headlight applications. The replacement chart covers 2011 to 2015 model years 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 D1S is a High Intensity Discharge (HID) xenon bulb, meaning it produces light by passing an electrical arc through xenon gas rather than heating a filament. It operates at 85 volts and 35 watts.
Both the high beam and low beam positions of the Mercedes-Benz SLS AMG use the D1S bulb across all model years from 2011-2015, making it the sole bulb type in the headlight system.
The D1S carries the PK32d-2 base designation, which is a specific keyed connector format. This base type is not interchangeable with other HID bases such as D2S, D3S, or D4S, even though those bulbs share similar physical proportions.
A defining characteristic of the D1S is its integral ignitor, meaning the high-voltage starting component is built directly into the bulb unit itself. This differs from D2S bulbs, which rely on a separate external ignitor within the ballast assembly.
The D1S is rated under the ECE standard, a regulatory framework recognized across Europe and many international markets. This designation governs the bulb's photometric output, color temperature, and construction requirements.
D1S bulbs are designed exclusively for projector-type headlight housings, which use a lens and shield to produce a controlled, sharp light cutoff. They are not suited for reflector-style housings.
Because the D1S operates at 85 volts, the headlight system on the 2011-2015 SLS AMG requires a compatible HID ballast to step up voltage from the vehicle's 12-volt electrical system before the arc can be struck.
