The Mercedes-Benz ML63 AMG parking light requires a 12961 bulb size for proper installation and function. Data for the specified component covers the period from 2007 through 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz ML63 AMG uses the 12961 bulb for its front parking light across all listed model years, spanning 2007-2015.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts with a 5-watt output.
The T10 designation refers to a tubular bulb roughly 10mm in width, commonly used in low-intensity automotive lighting positions such as parking lights and side markers.
The 12961 uses a W2.1x9.5d base, which is the standard wedge-type base for T10 bulbs. This base type relies on the bulb's wire leads to make electrical contact rather than a separate metal cap.
The W2.1x9.5d base is not interchangeable with bayonet or festoon base types, as the contact geometry differs fundamentally between those designs.
For the 2007 model year, the 12961 fitment is specifically noted as applying to vehicles equipped with halogen capsule headlamps, indicating that headlamp type is a relevant factor in confirming correct fitment for that year.
