Additional Notes

The GMC Canyon license plate bulb specifications reference two distinct part numbers across the model's production years: the 194 and the 12961.
Both the 194 and the 12961 share the same T10 miniature wedge form factor and operate on 12 volts, placing them in the same broad bulb family.
Despite their shared form factor, the two bulbs differ in wattage. The 194 is rated at 3.78W, while the 12961 is rated at 5W.
The 12961 is a Philips part number designation, whereas the 194 is an ANSI standard designation recognized across the United States and Canada.
The 12961 specifies a W2.1x9.5d base, which is the standard wedge base type associated with T10 miniature bulbs in automotive applications.
The GMC Canyon (2021-2024) uses the 194 bulb for the license plate position, while model years 2004-2020 reference the 12961.
Although both bulbs use a T10 wedge base, the wattage difference between the 194 and the 12961 is a relevant fitment consideration, as substituting one for the other may affect circuit load.
