Additional Notes

The Toyota FJ Cruiser map light specifications reference two bulb types across its model years: the 12961 and the 168. Both are T10 miniature wedge bulbs operating at 12 volts.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W.
The 168 is an ANSI standard designation recognized in the US and Canada, also a T10 miniature wedge bulb, rated at 12V and 4.9W.
The W2.1x9.5d base specification on the 12961 describes the physical wedge base format, where the numbers indicate the contact width and pin spacing of the bulb's base.
The 12961 is the more frequently specified bulb across the Toyota FJ Cruiser map light data, appearing in the 2008-2010, 2011, and 2014 model years.
The 168 is specified for the 2012-2013 Toyota FJ Cruiser map light position.
Although both the 12961 and 168 share the T10 form factor and near-identical wattage, they carry different part number systems, one being a Philips proprietary designation and the other an ANSI industry standard.
The 0.1W difference between the 12961 (5W) and the 168 (4.9W) reflects a minor variance in rated power output between the two otherwise closely matched bulb types.
