Additional Notes

The INFINITI Q60 glove box uses two distinct bulb types across its model years: the 158 and the 74, both classified under ANSI standards applicable to the US and Canadian markets.
The 158 bulb is a T10 miniature wedge type rated at 12V and 3W, while the 74 bulb is a T5 miniature wedge type rated at 12V and 1.4W. The T10 and T5 designations refer to the tubular envelope width, with T10 being physically larger than T5.
The 2021-2022 INFINITI Q60 glove box takes the 158 (T10) bulb, whereas the 2017-2020 model years use the 74 (T5) bulb.
The wattage difference between the two bulbs is notable: the 158 draws 3W compared to the 74's 1.4W, meaning the two are not electrically equivalent and are not interchangeable without consideration of the socket and circuit design.
Both bulb types use a wedge base, which means they are retained by friction within the socket rather than by a bayonet or screw mechanism. However, the T10 and T5 wedge bases differ in physical size and are not cross-compatible with each other's sockets.
The shift from the T5 (74) to the T10 (158) between the 2020 and 2021 model years represents a change in socket specification, meaning parts sourced for 2017-2020 vehicles are not suitable for 2021-2022 vehicles, and vice versa.
