Additional Notes

The Toyota Cressida trunk bulb specifications cover the 1985-1986 and 1989-1992 model years, with two distinct bulb sizes used across that span.
The 1989-1992 model years use the 194 bulb, while the 1985-1986 model years use the 168 bulb.
Both the 194 and 168 are ANSI-standardized miniature wedge bulbs sharing the T10 form factor and a 12-volt operating voltage.
The primary electrical difference between the two types is wattage: the 194 draws 3.78W, while the 168 draws 4.9W, making them non-identical in power consumption despite their shared physical format.
Because the 194 and 168 share the T10 wedge base, either bulb is physically capable of fitting the same socket, which creates a risk of installing the wrong wattage if the model year is not confirmed beforehand.
Substituting a 168 into a 1989-1992 Cressida trunk socket would result in higher-than-specified wattage draw, while fitting a 194 into a 1985-1986 socket would produce lower output than originally intended.
