Additional Notes

The Toyota Land Cruiser interior door bulb specifications cover model years 2003-2015, with two distinct bulb sizes used across that span: the 168 and the 194.
Both the 168 and 194 are ANSI-standardized miniature wedge bulbs sharing the same T10 form factor and 12-volt operating voltage, which means they are physically interchangeable in terms of socket fit.
Despite their shared socket type, the 168 and 194 differ in wattage. The 168 draws 4.9 watts, while the 194 draws 3.78 watts, making them electrically distinct and not direct equivalents for replacement purposes.
The Toyota Land Cruiser (2008-2015) uses the 168 bulb for the interior door position, with the exception of 2012, which is not listed in the specifications.
The 194 bulb is specified for the Toyota Land Cruiser across model years 2003-2007, covering the earlier portion of the listed range.
The T10 wedge base is a widely used miniature bulb format in automotive interior applications, held in place by the tension of the socket rather than a bayonet or screw mechanism.
Because both bulb types share the T10 socket, substituting a 194 for a 168 or vice versa is physically possible, but the wattage difference may affect brightness output relative to the original factory specification.
