Additional Notes

The Mazda CX-7 map light uses two distinct bulb sizes across its model years, with the 12961 appearing in 2007-2011 and the 168 appearing in 2012.
Both the 168 and 12961 are miniature wedge bulbs sharing the T10 form factor, meaning they occupy the same physical bulb family despite carrying different part designations.
The 12961 is a Philips-assigned part number rather than an ANSI industry standard designation, and it specifies a W2.1x9.5d base, which is the standard wedge base type used in low-voltage automotive interior applications.
The 168 carries an ANSI standard designation recognized across the United States and Canada, operating at 12V with a rated wattage of 4.9W.
The 12961 operates at 12V and 5W, placing its power draw marginally higher than the 168 at 4.9W, a difference of 0.1W.
Although both bulbs share the T10 form factor, the 168 and 12961 are listed under separate model years for the CX-7, and substitution between them warrants attention to base compatibility and wattage tolerance of the socket.
The W2.1x9.5d base designation on the 12961 describes a wedge base with a 2.1mm wire width and a 9.5mm insertion depth, which is the dimensional standard governing physical fitment in the lamp housing.
