Additional Notes

The Toyota Sequoia interior door position uses one of two bulb types across the 2005-2020 model years: the 168 and the 194, both of which are ANSI-standardized miniature wedge bulbs classified under the T10 form factor and rated at 12 volts.
The 168 bulb is specified for the 2008-2020 Sequoia interior door position and operates at 4.9 watts, making it the more power-consuming of the two types listed.
The 194 bulb is specified for the 2005-2007 Sequoia interior door position and operates at 3.78 watts.
Although the 168 and 194 share the same T10 wedge base and 12-volt operating voltage, their wattage ratings differ, and the two types are not confirmed as interchangeable within these specifications.
The T10 wedge base is a common automotive bulb format in which the electrical contacts are formed directly from the glass envelope base, requiring no separate metal shell or bayonet pins for installation.
Both the 168 and 194 carry ANSI standardization applicable to the US and Canadian markets, meaning their electrical and physical characteristics conform to a defined industry specification rather than a proprietary standard.
