Additional Notes

Both bulb types specified for the Mitsubishi Expo license plate position belong to the T10 miniature wedge family, which uses a wedge-shaped base that seats directly into a socket without pins or a separate base.
The T10 form factor is shared between the 168 and 194 bulbs, meaning both occupy the same physical socket type, though this physical similarity does not make them interchangeable without accounting for wattage differences.
The 168 bulb operates at 12V and 4.9W, while the 194 operates at 12V and 3.78W, representing a difference of approximately 1.12W between the two ratings.
Both bulbs conform to ANSI standards recognized in the United States and Canada, indicating standardized electrical and physical tolerances across manufacturers producing these part numbers.
The 1995 Mitsubishi Expo requires the 168 bulb for the license plate position, which draws more wattage than the 194 used in prior model years.
The 1992-1994 model years share the 194 bulb specification for the license plate position, indicating consistent fitment across those three years.
A wattage mismatch between the 168 and 194 could affect socket load tolerances, as the socket and wiring in each model year are paired to the wattage rating specified for that year.
