Additional Notes

The 194 bulb is the specified trunk bulb size for the Toyota GR86 across the 2022-2023 model years.
The 194 designation follows the ANSI standard used in the United States and Canada, classifying it as a miniature wedge-base bulb in the T10 form factor.
The T10 wedge base is a push-in, pin-free design where the glass envelope itself forms the electrical contact, seating directly into a corresponding socket without requiring a separate connector.
The 194 bulb operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of interior and cargo area lighting applications.
The T10 form factor is shared by a wide range of bulbs across different ANSI designations, meaning physical fitment alone does not confirm electrical compatibility with the 194 specification.
