Additional Notes

The 158 and 194 are both ANSI-standardized miniature wedge bulbs sharing the T10 form factor and a 12-volt operating voltage, making them physically interchangeable in terms of socket fitment.
Despite the shared T10 socket, the two bulb types differ in wattage: the 158 draws 3 watts, while the 194 draws 3.78 watts, meaning they are not electrically identical replacements for one another.
The INFINITI Q60 uses the 158 bulb for the trunk across the 2014-2015 and 2017-2022 model years, making it the predominant trunk bulb specification across this vehicle's production range covered in these specifications.
The 2022 Q60 trunk specification calls for the 194 bulb rather than the 158, representing a wattage increase of 0.78 watts compared to all other listed model years.
Both the 158 and 194 carry ANSI standardization applicable to the US and Canadian markets, indicating conformance to a recognized North American bulb classification system.
The T10 wedge base is a capless design in which the bulb is held in its socket by the tension of two wire contacts rather than a threaded or bayonet-style base, a construction common to low-wattage interior and auxiliary lighting applications.
