Additional Notes

The Subaru Impreza license plate bulb specifications cover model years 1993 through 2024, with three distinct bulb sizes appearing across that span: 12961, 168, and 194.
All three bulb sizes belong to the T10 miniature wedge family, meaning they share the same general form factor despite carrying different part numbers and wattage ratings.
The 194 bulb is an ANSI-standard miniature wedge type rated at 12V and 3.78W, and it is specified for the Subaru Impreza across model years 1993-2001.
The 168 bulb is also an ANSI-standard T10 miniature wedge type, rated at 12V and 4.9W, and it applies to model years 2015-2019.
Although the 168 and 194 are both ANSI-standard T10 wedge bulbs operating at 12V, their wattage ratings differ, with the 168 drawing approximately 1.1W more than the 194.
The 12961 is a Philips part number rather than an ANSI designation, and it uses a W2.1x9.5d base, which is the standard wedge base specification for T10 bulbs, rated at 12V and 5W.
The 12961 is specified exclusively for the 2024 Subaru Impreza, making it the highest-wattage license plate bulb among the three types listed in these specifications.
Because the 168 and 194 share the T10 wedge form factor and the same 12V operating voltage, physical fitment in the socket may be possible across those two sizes, though their differing wattage ratings mean they are not electrically identical replacements for one another.
The W2.1x9.5d base designation on the 12961 is the IEC standard notation for the common T10 wedge base, indicating a wedge width of 2.1mm and a pin length of 9.5mm.
The ANSI standard designation on the 168 and 194 bulbs indicates those sizes conform to a shared North American industry specification, applicable in both the United States and Canada.
