Additional Notes

The 168 bulb is the specified trunk bulb size for the Toyota 86 across the 2017-2020 model years.
The 168 bulb follows the ANSI standard, which is the American National Standards Institute classification system used to designate bulb types in the United States and Canada.
The 168 is a T10 miniature wedge bulb, a form factor defined by its wedge-shaped base that connects directly into a socket without a separate metal cap or pins.
The T10 designation refers to the bulb body width expressed in eighths of an inch, placing the 168 in a widely used size class for low-intensity interior and auxiliary lighting positions.
The 168 operates at 12 volts and 4.9 watts, consistent with standard automotive low-voltage electrical systems and typical of low-draw interior lighting applications such as trunk illumination.
The T10 wedge base type is shared across numerous bulb variants, so substitution with other T10-designated bulbs requires verification that voltage and wattage ratings match the 168 specification to avoid electrical incompatibility.
