Additional Notes

The 7444NA is an ANSI-standardized dual-filament wedge bulb in the T20 form factor, rated at 12V with a 21W/5W output split between its two filaments. Its natural amber glass produces a yellow-tinted light output without the need for an amber-colored lens or housing.
The 12961 is a Philips part number designating a miniature single-filament T10 wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. The W2.1x9.5d base is a metric wedge standard that defines the pin width and contact spacing of the bulb's base.
The Nissan LEAF uses the 7444NA for the front parking light in the 2019-2020 and 2022-2023 model years, and the 12961 for the 2011-2018 model years.
The 7444NA and 12961 are not interchangeable. The T20 and T10 form factors differ in physical size, and the 7444NA carries a dual-filament configuration while the 12961 is a single-filament bulb, making the two electrically and physically incompatible.
The 7444NA's dual-filament design means it is capable of serving two lighting functions from a single socket, with the 21W filament typically assigned to a higher-intensity function and the 5W filament to a lower-intensity one.
The transition from the 12961 to the 7444NA between the 2018 and 2019 model years of the LEAF represents a shift from a T10 single-filament bulb to a T20 dual-filament bulb in the front parking light position.
