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 uses the 12961 bulb for interior door lighting across the 2022-2023 model years.
At 5 watts, the 12961 operates at a low power draw, which is typical for interior courtesy and door lighting applications.
The T10 designation refers to the bulb's tubular envelope size, expressed in eighths of an inch, placing its width at approximately 10/8 of an inch.
The W2.1x9.5d base specification is standardized, meaning compatible T10 wedge bulbs from other manufacturers sharing that base type are generally interchangeable with the 12961 in this application.
