Additional Notes

The Nissan GT-R trunk uses two distinct bulb sizes across its model years: the 158 for 2009-2020 and the 194 for 2021 and 2023.
Both the 158 and 194 are ANSI-standardized miniature wedge bulbs of the T10 type, meaning they share the same wedge-base form factor and are rated for 12-volt automotive electrical systems.
Despite their shared T10 wedge base, the 158 and 194 differ in wattage. The 158 draws 3W, while the 194 draws 3.78W, which affects their light output and thermal load on the socket.
The wattage difference between the two bulbs means they are not directly interchangeable without consideration, even though their physical base type is the same T10 wedge format.
The 158 bulb is the specification for the Nissan GT-R trunk across the longest span of model years in the data, covering 2009-2020.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized performance and dimensional tolerances within those markets.
