Additional Notes

The INFINITI QX80 uses two different bulb sizes for the license plate position across its model years: the 12961 for 2021-2024 and the 168 for 2014-2020.
Both the 12961 and 168 are T10 miniature wedge bulbs, meaning they share the same physical envelope shape and wedge-style base format.
Despite the shared T10 form factor, the two bulbs differ in their base designation. The 12961 carries a W2.1x9.5d base specification, while the 168 is defined under the ANSI standard used in the US and Canada.
The 12961 is a Philips part number rather than an ANSI or international trade number, which means sourcing equivalent replacements may require cross-referencing to confirm compatibility.
Both bulbs operate at 12 volts, consistent with standard automotive electrical systems.
The wattage between the two types is nearly identical. The 12961 is rated at 5W and the 168 at 4.9W, a difference of 0.1W.
The 168 is governed by ANSI standards, which defines its electrical and physical tolerances for the North American market.
Because the 12961 and 168 share the T10 wedge form, physical fitment into the socket housing may appear similar, but the differing base standards mean substitution between the two types is not confirmed as interchangeable by the specifications.
