Additional Notes

The Jaguar XFR uses the 12961 bulb for the map light across all available model years, spanning 2010-2015.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor.
T10 refers to the bulb's tubular shape, with the number indicating a width of 10 millimeters.
The 12961 uses a W2.1x9.5d wedge base, which is a pinless base type that is held in place by friction within the socket rather than by pins or a bayonet mechanism.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles.
The 12961 carries a 5-watt power rating, placing it in the low-wattage range typical of interior courtesy and reading lights.
The W2.1x9.5d base designation is standardized, meaning aftermarket or OEM-equivalent T10 bulbs sharing that base type are generally interchangeable with the 12961 in this application.
