Additional Notes

The Mitsubishi Diamante uses two distinct bulb sizes for the license plate position across its production run: the 168 and the 194, both of which are ANSI-standardized miniature wedge bulbs of the T10 type rated at 12 volts.
Although both bulbs share the same T10 wedge form factor, they are not interchangeable due to their differing wattage ratings. The 168 draws 4.9 watts, while the 194 draws 3.78 watts.
The Mitsubishi Diamante (1995-2004) requires the 168 bulb for the license plate position, covering a span of ten model years.
The 1992-1994 Diamante uses the 194 bulb for the license plate position, which carries a lower wattage than the 168 used in later model years.
The T10 wedge base is a common miniature bulb format in which the glass envelope is fused directly into a plastic wedge-shaped base, eliminating the need for a separate metal contact pin.
Both the 168 and 194 are governed by ANSI standards applicable in the United States and Canada, meaning their electrical and physical characteristics conform to a defined specification rather than varying by manufacturer.
The wattage difference between the 168 and 194 reflects a measurable gap in light output, with the 168 producing a modestly brighter illumination at the license plate position.
