Additional Notes

The INFINITI QX60 uses two distinct bulb types for the sun visor across its model years: the 12961 (T10) for 2022-2023 and the 37 (T5) for 2014-2016.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, operating at 12V and rated at 5W, with a W2.1x9.5d base.
The W2.1x9.5d base is a wedge-type connector where the bulb's glass envelope itself acts as the contact point, requiring no separate metal base pins.
The 37 is an ANSI-standardized bulb number recognized across the US and Canada, designating a T5 miniature wedge type rated at 12V and 1W.
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 at 10/8 inch versus 5/8 inch.
The wattage difference between the two types is significant: the 12961 draws 5W while the 37 draws 1W, meaning the two bulbs are not interchangeable despite both using wedge-style bases.
The base configurations also differ between the two types, as the T10 uses a W2.1x9.5d base while the T5 uses a narrower wedge profile, further preventing cross-fitment between the 2014-2016 and 2022-2023 model years.
