Additional Notes

The Toyota Tacoma map light uses the 168 bulb size across all listed model years from 2005 to 2023.
The 168 bulb is classified as a T10 miniature wedge type, which refers to its wedge-shaped base that seats directly into a socket without requiring a separate holder or pins.
This bulb operates at 12 volts and draws 4.9 watts, placing it in the low-wattage range typical of interior courtesy and map lighting applications.
The 168 designation follows ANSI standardization recognized in both the United States and Canada, meaning the specification reflects a formally defined bulb standard rather than a proprietary sizing.
Because the T10 wedge base is a widely shared form factor, multiple bulb part numbers beyond the 168 may physically fit the same socket, though electrical compatibility depends on matching voltage and wattage ratings.
The uninterrupted use of the 168 across the 2005-2023 model years of the Toyota Tacoma indicates socket and housing consistency across those generations for the map light position.
