Additional Notes

The 194 and 12961 bulbs both follow the T10 miniature wedge form factor, meaning they share the same general wedge-style base configuration used in low-current interior lighting applications.
Despite the shared T10 form factor, the two bulbs differ in wattage. The 194 operates at 3.78W, while the 12961 operates at 5W, representing a difference that can affect socket compatibility and thermal load in confined interior spaces.
The 194 is designated under the ANSI standard used in the United States and Canada, whereas the 12961 is a Philips part number referencing a bulb with a W2.1x9.5d base, which is a metric base designation common in European automotive applications.
The Alfa Romeo Giulia used the 12961 bulb for the glove box across the 2017-2020 model years, while the 194 bulb appears in the 2021-2023 model years.
For the 2021-2022 model years, the 194 bulb fitment is specifically noted as applying to vehicles equipped with HID headlights, indicating that headlight type is a relevant variable in determining the correct glove box bulb for those years.
Both bulbs operate on a 12V electrical system, which is standard across conventional passenger vehicle platforms.
The W2.1x9.5d base specification of the 12961 denotes a wedge base with a 2.1mm wire contact width and a 9.5mm insertion depth, distinguishing it at the base level from the 194 despite the shared T10 body type.
