Additional Notes

The 194 is an ANSI-standardized bulb used in the United States and Canada. It is a T10 miniature wedge type rated at 12V and 3.78W, and it serves as the glove box bulb in the Alfa Romeo Stelvio for the 2021-2023 model years.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It fits the Stelvio glove box for the 2018-2020 model years.
Both the 194 and the 12961 share the T10 miniature wedge form factor, meaning they occupy the same physical bulb family. However, their wattage ratings differ, with the 194 drawing 3.78W and the 12961 drawing 5W.
The W2.1x9.5d base designation on the 12961 describes a specific wedge base standard where 2.1 refers to the wire contact width in millimeters and 9.5 refers to the base length in millimeters. This base type is common across many T10 wedge bulbs.
Despite sharing the T10 form factor, the 194 and 12961 are not listed as interchangeable across all Stelvio model years in these specifications, as each is assigned exclusively to its respective year range.
