Additional Notes

The 9003 bulb is the most frequently specified type across the G55 AMG's headlight history, appearing in both high beam and low beam positions from 2003 through 2010 on halogen capsule headlamp configurations. It is a dual-filament halogen bulb operating at 12V with a 60W high beam filament and a 55W low beam filament, fitted with a P43t base, and follows the ANSI standard used in the US and Canada.
The D1S bulb is an HID xenon discharge type operating at 85V and 35W, built to ECE standards for worldwide use. It incorporates an integral ignitor and uses a PK32d-2 base, and is designed exclusively for projector-type housings. On the Mercedes-Benz G55 AMG, it serves both high beam and low beam functions in 2011, and also appears in HID headlamp configurations for 2008-2010.
The D2S bulb shares the same 85V, 35W operating characteristics as the D1S and is likewise an ECE-standard HID xenon type for projector housings, but it uses a P32d-2 base and requires a separate external ignitor rather than an integrated one. On the G55 AMG, it is specified for low beam positions in HID headlamp configurations from 2003-2006.
The H7 bulb is a single-filament halogen type rated at 12V and 55W, using a PX26d base under ECE standards. On the G55 AMG, it appears exclusively in the high beam position within HID headlamp configurations from 2003-2010, functioning as a dedicated high beam alongside a separate HID low beam bulb.
Vehicles equipped with HID headlamps from 2003-2006 use a split-type arrangement in which the high beam is served by the H7 halogen bulb and the low beam by the D2S xenon bulb. This means the two beam positions are not interchangeable and require different bulb types within the same headlamp system.
For 2008-2010 HID headlamp configurations, the high beam position shifts from the H7 and D2S pairing to D1S for both high and low beams, while the H7 remains listed only for the high beam. The low beam in this period no longer references D2S, indicating a change in the HID system used during those years.
The 2007 model year lists only the 9003 bulb for both high and low beams, with no HID headlamp variant specified, which distinguishes it from the surrounding years that include HID options.
Because the G55 AMG was offered with both halogen capsule and HID headlamp configurations across multiple years, selecting the correct bulb type depends strictly on which headlamp system is installed, as the halogen and HID variants within the same year are not interchangeable with one another.
