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 fitting, meaning the bulb is held in place by tension from the socket rather than by a bayonet or screw mechanism.
The Toyota Corolla Cross (2022-2023) uses the 12961 bulb for the front dome light position.
The T10 designation refers to the bulb's tubular form factor, with the number indicating a width of 10 eighths of an inch, a standard sizing convention in miniature automotive bulbs.
At 5 watts and 12 volts, the 12961 operates at a relatively low power draw, consistent with interior courtesy lighting applications.
