Additional Notes

The Mitsubishi 3000GT uses two distinct bulb sizes for the license plate position across its model years: the 168 and the 194.
Both the 168 and 194 are ANSI-standardized miniature wedge bulbs sharing the T10 form factor and a 12-volt operating voltage, which means they are physically identical in base type.
Despite sharing the same T10 wedge base, the 168 and 194 differ in wattage. The 168 operates at 4.9 watts, while the 194 operates at 3.78 watts, making them electrically non-equivalent.
The Mitsubishi 3000GT (1994-1999) uses the 168 bulb for the license plate position.
The 1991-1993 model years use the 194 bulb instead, representing a specification change at some point in the 1993-1994 production transition.
Because the 168 and 194 share the T10 wedge base, one may physically fit in the socket intended for the other, but the wattage difference means substituting one for the other falls outside the manufacturer specification.
