Additional Notes

The INFINITI QX60 map light specifications cover model years 2014-2019 and reference three distinct bulb sizes: 168, 12961, and 89.
The 89 bulb is an ANSI-standard single-filament type with a BA15s bayonet base, rated at 12V and 13W. It is a lower wattage variant of the 1156 bulb family.
The 12961 is a Philips part number designation for a miniature wedge bulb in the T10 form factor, using a W2.1x9.5d base and rated at 12V, 5W.
The 168 is an ANSI-standard T10 miniature wedge bulb rated at 12V and 4.9W, recognized across both the US and Canadian markets.
Both the 168 and 12961 share the T10 form factor, though they carry different designations. The 168 follows the ANSI numbering system while the 12961 follows Philips proprietary numbering.
For the 2014-2018 QX60, the front map light position uses the 89 bulb with its BA15s bayonet base, which is physically incompatible with the wedge-style sockets used in the side positions.
The side map light positions for the 2014-2018 QX60 use the 12961, while the 2019 QX60 uses the 168 across its map light fitment. These two bulbs, though both T10 wedge types, carry separate part designations and differ slightly in wattage.
The BA15s bayonet base of the 89 bulb is mechanically distinct from the wedge base of the T10 bulbs, meaning the 89 cannot be substituted into positions specified for the 168 or 12961.
