Additional Notes

The Ferrari 458 Italia uses the 12961 bulb for the license plate position across all listed model years, spanning 2010-2015.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12 volts and rated at 5 watts.
The T10 designation refers to the bulb's tubular shape, with the number indicating a width of 10 millimeters across the glass envelope.
The base type is W2.1x9.5d, which is the standard wedge base used across a wide range of miniature automotive lighting applications, including license plate, courtesy, and instrument panel positions.
The W2.1x9.5d base relies on direct contact between the bulb's wedge-shaped glass pinch and the socket, with no separate metal connector pins, making fitment dependent on socket geometry rather than a keyed locking mechanism.
Because the 12961 is a Philips-branded part number rather than an industry-standard ANSI or ECE bulb code, equivalent bulbs from other manufacturers must share the same T10 form factor, W2.1x9.5d base, 12V rating, and 5W output to be considered interchangeable.
