Additional Notes

The Mazda CX-7 license plate position uses T10 miniature wedge bulbs across all model years covered in the specifications, from 2007 through 2012.
Two distinct bulb sizes appear in these specifications: the 168, an ANSI-standard designation used in the United States and Canada, and the 12961, a Philips part number designation.
The 168 bulb operates at 12 volts with a rated output of 4.9 watts, while the 12961 operates at 12 volts with a rated output of 5 watts.
The 12961 carries a W2.1x9.5d base specification, which is the standard base type for T10 miniature wedge bulbs and describes the contact width and pin spacing of the wedge base.
The Mazda CX-7 (2007-2011) uses the 12961 bulb for the license plate position across five consecutive model years.
The 2012 model year transitions to the 168 bulb, which differs from the 12961 used in prior years despite both being T10 wedge-type bulbs.
Although both the 168 and 12961 share the T10 wedge form factor, the 0.1-watt difference in rated power and the distinct part number designations indicate they are not catalogued as interchangeable in these specifications.
