Additional Notes

The Honda HR-V map light uses two distinct bulb types across its model years: the 12961 and the 168, both of which fall under the T10 miniature wedge form factor.
The T10 designation refers to a tubular bulb body approximately 10mm wide, commonly used in low-current interior lighting applications such as map, dome, and courtesy lights.
The 12961 is a Philips part number rather than an ANSI industry standard, and it specifies a W2.1x9.5d wedge base operating at 12V and 5W.
The 168 is an ANSI-standardized bulb recognized across the US and Canadian markets, also a T10 wedge type, rated at 12V and 4.9W.
The Honda HR-V (2016-2018 and 2021-2022) uses the 12961 bulb for the map light position.
The 2019-2020 model years use the 168 bulb instead.
Although both bulbs share the T10 wedge form factor, the 12961 draws 5W while the 168 draws 4.9W, reflecting a slight difference in power consumption between the two types.
The W2.1x9.5d base designation on the 12961 describes the physical wedge base geometry, where W2.1 refers to the wire contact width and 9.5d refers to the base depth in millimeters.
Because the 12961 is a manufacturer-specific part number and the 168 is an ANSI standard, cross-referencing between the two requires confirming that base geometry and voltage ratings are compatible for the specific model year in question.
Substituting a 168 bulb into a position specified for the 12961, or vice versa, carries a fitment risk despite the shared T10 body type, given the differing wattage and base specification conventions.
