Additional Notes

The Mazda 929 license plate bulb specifications cover model years 1988-1995, with two distinct bulb sizes used across that range: the 194 and the 168.
Both the 194 and 168 are ANSI-standardized miniature wedge bulbs classified under the T10 form factor, operating on a 12-volt circuit.
Although the 194 and 168 share the same T10 wedge base and voltage rating, they are not identical. The 168 draws 4.9 watts, while the 194 draws 3.78 watts, making the two bulbs non-interchangeable despite their physical similarities.
The 168 bulb is specified for the Mazda 929 across model years 1988-1991 and again for 1994.
The 194 bulb applies to the 929 for model years 1992-1993 and 1995.
The 1994 model year returns to the 168 specification after two consecutive years of 194 fitment, meaning the bulb requirement does not follow a single uninterrupted progression across the full production run.
