Additional Notes

The Honda Passport stepwell position uses two distinct bulb types across its model years: the 194 for 2019-2024 and the 12961 for 1995-2002.
Both the 194 and the 12961 share the same T10 miniature wedge form factor and operate on 12 volts, placing them in the same broad bulb family.
Despite the shared T10 form factor, the two bulbs are not identical in power draw. The 194 is rated at 3.78 watts, while the 12961 draws 5 watts, a difference that can affect socket load and brightness.
The 194 is an ANSI-standardized bulb recognized across the United States and Canada, meaning it is produced by multiple manufacturers under that designation.
The 12961 carries a Philips part number rather than an ANSI designation, and it specifies a W2.1x9.5d base, which is the standard wedge base type used in T10 miniature bulbs.
Because the 12961 is identified by a manufacturer part number, sourcing an equivalent from another brand requires confirming that the replacement matches the W2.1x9.5d base and 5-watt rating.
The T10 wedge base on both bulbs is a pinless design that seats by friction, meaning the bulb is held in place by the socket walls rather than by locking tabs or pins.
