Additional Notes

The Honda Passport trunk bulb specifications reference two bulb types across the 2019-2024 model years: the 12961 and the 168.
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.
Both bulbs share the T10 form factor and W2.1x9.5d wedge base type, which is a small, pinless base where the glass envelope itself makes the electrical contact.
The wattage difference between the two bulbs is 0.1W, with the 12961 drawing slightly more power than the 168.
The Honda Passport (2021-2024) uses the 12961 bulb for the trunk position.
The 2019-2020 model years use the 168 bulb for the same trunk position.
The 12961 and 168 are not designated as interchangeable within these specifications, as they carry different part number standards despite sharing the T10 form factor.
