Additional Notes

The Toyota MR2 instrument panel uses two bulb types across its model years: the 194 and the 74, both of which are ANSI-standard miniature wedge bulbs rated for 12-volt systems.
The 194 is a T10 wedge bulb rated at 3.78 watts, while the 74 is a T5 wedge bulb rated at 1.4 watts. The two types are not interchangeable due to differences in physical size and wattage.
The 194 bulb is the more widely used of the two across the Toyota MR2 instrument panel specifications, appearing in the 1985, 1987-1989, and 1992-1995 model years.
The 74 bulb is specified for the 1986 and 1991 model years, making it the less frequently called-for type in this application.
The T5 designation of the 74 bulb refers to a tube width of 5/8 inch, while the T10 designation of the 194 refers to a tube width of 10/8 inch (1.25 inches), reflecting a meaningful size difference between the two bulb families.
Because the 1991 Toyota MR2 uses the 74 rather than the 194 specified for the surrounding model years, substituting a 194 in that application would result in an incorrect fit.
