The Mercedes-Benz C63 AMG parking light requires a bulb size of 12961 for the specific lighting components. Data for the provided specifications covers the range from 2008 to 2014.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mercedes-Benz C63 AMG uses the 12961 bulb for the front parking light across all model years from 2008-2014.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and 5 watts.
The T10 designation refers to a tubular bulb roughly 10mm wide, commonly found in low-intensity automotive lighting positions such as parking lights and courtesy lights.
The W2.1x9.5d base is a wedge-style base where the electrical contacts are made through the glass pinch at the bottom of the bulb rather than through a metal cap, which is typical of T10 miniature bulbs.
At 5 watts, the 12961 is a low-wattage bulb suited for always-on or daytime parking light functions where heat and power draw are kept minimal.
The C63 AMG with Halogen Capsule Headlamps also specifies the 12961 for the front parking light across the full 2008-2014 model year range, matching the standard fitment.
The consistent use of the 12961 across both the standard and Halogen Capsule Headlamp configurations indicates that the headlamp type does not alter the front parking light bulb requirement on this vehicle.
