Additional Notes

The Mazda 626 license plate bulb specifications cover model years 1979 through 2002, with three distinct bulb types used across that span: the 168, 194, and 89.
The 168 bulb is the most widely used type across the Mazda 626 lineup, fitting model years 1986 through 2001 with the exception of 1992, as well as 1985 and earlier years down to 1979 being covered by different types.
The 168 is an ANSI-standard miniature wedge bulb in the T10 form factor, operating at 12 volts and drawing 4.9 watts, making it a low-power lamp suited for illumination tasks such as license plate lighting.
The 194 bulb shares the same T10 wedge base as the 168 and operates at the same 12-volt supply, but draws only 3.78 watts, making it a lower-wattage unit within the same physical family.
The 1992 Mazda 626 is the sole model year in the specifications to use the 194 bulb for the license plate position, setting it apart from the surrounding years that use the 168.
Because the 168 and 194 share the T10 wedge base, they are physically interchangeable in terms of socket fit, but their wattage ratings differ, which is a relevant consideration when selecting a replacement.
The 89 bulb is specified for the Mazda 626 from 1979 through 1985, representing a physically distinct design from the T10 wedge types used in later years.
The 89 uses a BA15s single-contact bayonet base rather than a wedge base, meaning it is not interchangeable with the 168 or 194 without a socket adapter or modification.
At 13 watts, the 89 draws considerably more power than either the 168 or 194, as it is described as a lower-wattage variant of the 1156, which is a bulb type commonly associated with turn signal and brake light applications.
All three bulb types in these specifications conform to ANSI standards applicable in the United States and Canada.
