Additional Notes

The INFINITI QX80 uses the 12961 bulb for its map light across the 2014-2021 model years.
The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor.
T10 refers to the bulb's tubular shape, with the number indicating a width of 10 millimeters.
The 12961 uses a W2.1x9.5d base, which is the standard wedge-type base common to many automotive interior lighting applications.
The bulb operates at 12 volts and 5 watts, consistent with low-power interior lighting requirements in passenger vehicles.
The W2.1x9.5d base type is not compatible with bayonet or festoon-style sockets, so substitutions must match this specific base configuration.
The T10 wedge format is widely used across automotive interior lighting, meaning aftermarket equivalents from other manufacturers are generally available under different part numbers while sharing the same base and electrical ratings.
