Additional Notes

The Ram 1500 Classic glove box uses two distinct bulb types across its model years: the 194 and the 12961, both of which share the T10 miniature wedge form factor and a 12-volt operating voltage.
The 194 is an ANSI-standardized bulb recognized across the United States and Canada, rated at 12V and 3.78W, and it fits the 2019-2021 Ram 1500 Classic glove box position.
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, and it applies to the 2023 model year.
Although both bulbs share the T10 wedge form factor and the same base type, the 12961 draws approximately 1.22W more than the 194, reflecting a difference in power consumption between the two part numbers.
The W2.1x9.5d base specification of the 12961 describes a wedge-style contact with a 2.1mm width and a 9.5mm insertion depth, which is the standard geometry for T10 miniature wedge bulbs.
Because the 194 carries an ANSI designation, it is produced by multiple manufacturers and is widely available as a cross-compatible part, whereas the 12961 is identified by a Philips-specific part number.
The shared T10 wedge base between the 194 and 12961 means both bulbs are physically insertable into the same socket type, though the wattage difference is a relevant factor in fitment decisions.
