Additional Notes

The Mazda 323 license plate bulb specifications cover model years 1986-1994, split across two distinct bulb types depending on the production era.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, conforming to ANSI standards applicable in the US and Canada. Its wedge base design means it is held in place by the socket itself rather than by a locking mechanism.
The 67 bulb uses a BA15s single-contact bayonet base and is rated at 12V and 8W. The bayonet mount is a twist-lock style fitting, which is physically incompatible with the wedge socket used by the 168.
The Mazda 323 (1992-1994) takes the 168 bulb for the license plate position.
The 1986-1991 model years use the 67 bulb, which draws notably more wattage than the 168 used in later years.
The 67 bulb is described as a lower wattage variant of the 1156. While the two share the BA15s bayonet base, the 1156 is rated at a higher wattage, making the two non-equivalent as direct replacements for each other.
The base type difference between the 168 wedge and the 67 bayonet means bulbs from the 1986-1991 specification are not physically interchangeable with those from the 1992-1994 specification.
Both the 168 and 67 are single-filament bulbs, which is standard for license plate lighting applications where no variable intensity is required.
Both bulb types operate on a 12V system, consistent with standard automotive electrical architecture across both production periods.
The 168 and 67 both carry ANSI designations, indicating they conform to standardized specifications for the North American market.
