Additional Notes

The Toyota Avalon uses the 168 bulb size for the interior door position across the 2005-2022 model years.
The 168 bulb is an ANSI-standardized type, meaning its electrical and physical specifications are governed by a recognized North American industry standard applicable in the United States and Canada.
This bulb belongs to the T10 miniature wedge family, a form factor defined by a wedge-shaped base that seats directly into a socket without a separate metal cap or pins.
The 168 operates at 12 volts, which is consistent with the standard electrical system voltage found in conventional passenger vehicles.
The rated wattage of the 168 is 4.9W, placing it in the low-power range typical of interior courtesy and door lighting applications.
The T10 wedge base is a widely produced form factor, and the 168 shares this base type with several other bulb numbers in the same family, such as the 194 and 147, though those variants differ in wattage and are not interchangeable without accounting for those electrical differences.
