Additional Notes

The Nissan Pathfinder sun visor uses two distinct bulb types across its model years: the 12961 (T10) for 2022-2023 and the 37 (T5) for 2013-2020.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12V and 5W with a W2.1x9.5d base.
The 37 is an ANSI-standard designation recognized in both the US and Canada, referring to a T5 miniature wedge bulb rated at 12V and 1W.
The T10 bulb used in 2022-2023 models draws five times the wattage of the T5 bulb used in earlier model years, reflecting a meaningful difference in power consumption between the two types.
The W2.1x9.5d base on the 12961 T10 bulb specifies a wedge-style contact with a 2.1mm wire width and a 9.5mm insertion depth, which is a standard wedge base configuration.
The T5 and T10 designations refer to the bulb's tubular width in units of one-eighth of an inch, making the T10 physically larger than the T5 and incompatible as a direct substitute.
Because the 37 and 12961 differ in both base size and wattage, they are not interchangeable, and fitting the wrong type to a Nissan Pathfinder sun visor socket risks either a poor fit or electrical mismatch.
