The Mercedes-Benz G500 parking light requires a bulb with the specific size 3893 for proper installation and function. Available data for the specified lighting component covers the period from 2002 through 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz G500 front parking light position uses two distinct bulb types across its model years, with the 12961 applying to 2006-2008 and the 3893 applying to 2002-2007.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb rated at 12V and 5W, fitted with a W2.1x9.5d base.
The T10 wedge form factor of the 12961 is a small, tapering plastic base that friction-fits directly into a socket without any rotation or locking mechanism.
The W2.1x9.5d base designation on the 12961 refers to a wedge base where 2.1 represents the base width in millimeters and 9.5 represents the insertion depth in millimeters.
The 3893 carries an ANSI standard designation recognized across the US and Canadian markets, rated at 12V and classified as a specialty application bulb.
The 3893 uses a BAY15d bayonet base, which is an offset dual-contact base requiring a push-and-twist installation and is not interchangeable with single-contact bayonet bases.
The dual-filament construction of the 3893 means the bulb contains two separate filaments within one envelope, each serving a distinct electrical circuit.
The 12961 and 3893 use entirely different base types, a wedge base versus a bayonet base, making them physically incompatible with each other's sockets.
The 2006-2007 model years carry entries for both the 12961 and the 3893, indicating that two separate fitment groups exist within those years rather than a single universal specification.
The 12961 entries are sourced specifically from fitment ID 144226, which represents a distinct vehicle configuration within the 2006-2008 production range.
