Additional Notes

The 12961 is the most frequently specified glove box bulb across the Ford Fiesta data, covering model years 2014-2018.
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.
The 194 is an ANSI standard designation recognized in the US and Canada, also a T10 miniature wedge bulb, rated at 12V and 3.78W.
Both the 12961 and 194 share the T10 wedge form factor, though their wattage ratings differ, with the 12961 drawing 5W and the 194 drawing 3.78W.
The Ford Fiesta (1979-1980) uses the 194 bulb for the glove box, while the 2014-2018 Fiesta uses the 12961, indicating these two bulb types are not interchangeable across those model year groups.
The W2.1x9.5d base specification on the 12961 refers to a wedge base with a 2.1mm wire width and a 9.5mm insertion depth, which defines its physical fitment into the socket.
The 194 carries an ANSI standardized designation, meaning it is produced by multiple manufacturers to a common specification, whereas the 12961 is identified by a Philips-specific part number.
