Additional Notes

The Mazda Protege map light uses the 168 bulb across 1993-2003, with the sole exception of the 1994 model year, which uses the 194 bulb instead.
Both the 168 and 194 are ANSI-standardized miniature wedge bulbs rated at 12 volts, sharing the same T10 wedge base form factor.
The T10 wedge base means both bulb types are physically compatible with the same socket, as the base design is identical between them.
Despite the shared base, the 168 and 194 differ in wattage. The 168 draws 4.9 watts while the 194 draws 3.78 watts, making them electrically distinct.
The lower wattage of the 194 bulb used in the 1994 Mazda Protege means it produces less light output than the 168 used in surrounding model years.
Because both bulbs share the T10 wedge base, a 168 can physically fit a 194 socket and vice versa, though the wattage difference should be noted before substituting one for the other.
