Additional Notes

The 194 bulb is the specified trunk bulb size for the Toyota Yaris across the 2013-2014 and 2018-2019 model years listed in these specifications.
The 194 bulb follows the ANSI standard, which is the recognized classification system for miniature bulbs used in the United States and Canada.
This bulb belongs to the T10 wedge family, a miniature wedge-base type that uses a tapering plastic base to secure itself directly into a socket without a separate metal holder or bayonet fitting.
The 194 operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of interior and cargo area lighting applications.
The T10 wedge base format is widely shared across many vehicle makes and models, though fitment should be confirmed against the specific socket housing in the Yaris before substituting an alternative bulb carrying the same base type.
