Additional Notes

The 12961 is a Philips part number designating a miniature wedge bulb in the T10 form factor, fitted with a W2.1x9.5d base and rated at 12 volts and 5 watts.
The 168 is an ANSI-standardized designation used in the US and Canada, also a T10 miniature wedge bulb, rated at 12 volts and 4.9 watts.
Both the 12961 and 168 share the T10 wedge form factor, though they carry different designations under separate standardization systems, one proprietary and one industry-wide.
The Honda HR-V uses the 12961 bulb for the dome light across the 2016-2018 and 2021-2022 model years.
The 2019-2020 Honda HR-V dome light takes the 168 bulb rather than the 12961 used in surrounding model years.
The wattage difference between the two bulbs is marginal, with the 12961 rated at 5 watts and the 168 at 4.9 watts, both operating on a 12-volt circuit.
The W2.1x9.5d base designation on the 12961 describes a wedge-type base where 2.1 refers to the wire contact width in millimeters and 9.5 refers to the base depth in millimeters.
Although both bulbs share the T10 form factor, substituting one for the other without confirming base and voltage compatibility for a specific model year may result in an improper fit.
