The Mercedes-Benz G55 AMG parking light requires a 3893 bulb size for proper installation and function within the lighting assembly. Data for the specified component covers the range from 2003 to 2007.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz G55 AMG front parking light position uses two distinct bulb types across its model years, with the 12961 and 3893 each serving specific year ranges.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The T10 wedge form factor is among the most widely used miniature bulb formats in automotive lighting, typically found in low-current positions such as parking lights, side markers, and interior lamps.
The W2.1x9.5d base designation refers to a wedge-style connection where the bulb's glass envelope itself acts as the retention mechanism, requiring no separate metal base to lock into the socket.
The 12961 bulb fits the Mercedes-Benz G55 AMG front parking light for the 2005-2011 model years.
The 3893 is an ANSI-standard bulb recognized in the United States and Canada, featuring a BAY15d bayonet base and a dual-filament configuration, rated at 12V.
A BAY15d bayonet base uses two offset pins to ensure the bulb is seated in a single correct orientation, which is a requirement for dual-filament bulbs where each filament serves a distinct function.
The 3893 bulb fits the front parking light position on the G55 AMG for the 2003-2007 model years.
The 12961 and 3893 are not interchangeable, as they differ in base type, filament count, and physical form factor, making socket compatibility a critical factor when selecting a replacement.
For the 2005-2007 model years, both the 12961 and 3893 are listed for the front parking light position, indicating that the applicable bulb type depends on the specific vehicle configuration within those years.
