Additional Notes

The 12961 is a Philips part number designating a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12 volts and 5 watts.
The W2.1x9.5d base is a wedge-type connection, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
The Porsche 718 Spyder uses the 12961 bulb for the trunk across the 2021-2024 model years.
The 2020 718 Spyder specifies the 12961 bulb only on vehicles without the Interior light package, indicating that the package configuration affects trunk bulb fitment for that year.
The T10 designation refers to a tubular bulb form factor approximately 10mm wide, a size widely used in low-intensity interior lighting applications such as trunk and courtesy illumination.
At 5 watts, the 12961 operates as a low-draw incandescent source, a characteristic typical of interior convenience lighting where extended illumination without engine load is a practical consideration.
