Additional Notes

The Porsche Boxster uses the 12961 bulb size for the dome light across all listed model years from 1997-2012.
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 cabin lighting applications.
The W2.1x9.5d base type is not universally interchangeable with other wedge base configurations, as variations in base width and pin spacing exist across different wedge bulb families.
