Additional Notes

The Aston Martin DBS uses the 12961 bulb for its license plate lighting across the 2008-2012 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, which is one of the most widely used bulb types in automotive auxiliary lighting applications.
The T10 designation refers to the bulb's tubular shape, with the number indicating a width of roughly 10 millimeters, making it a compact unit suited for small lamp housings such as license plate assemblies.
The 12961 operates at 12 volts and 5 watts, which is consistent with standard low-current auxiliary bulb ratings found across a broad range of vehicle lighting positions.
The base type is W2.1x9.5d, a wedge-style base that relies on friction and contact pressure rather than a bayonet or screw mechanism to secure the bulb within its socket.
The W2.1x9.5d base specification is a precise fitment detail, and substituting a bulb with a different base type risks poor electrical contact or physical incompatibility with the DBS lamp socket.
Because the same 12961 bulb is specified across all five listed model years of the DBS, a single bulb type covers the full 2008-2012 range without variation.
