Additional Notes

The 158 bulb is the glove box bulb size across all listed model years of the Infiniti Q50, spanning 2018-2024.
The 158 is classified as a T10 miniature wedge bulb operating at 12 volts and 3 watts, conforming to ANSI standards recognized in the United States and Canada.
The T10 designation refers to the bulb's tubular shape, with the number indicating a width of 10 eighths of an inch. The wedge base type means the glass envelope itself acts as the retention mechanism, with no separate metal base or pins.
At 3 watts, the 158 draws relatively low current, which is consistent with its application in a small interior illumination role such as a glove box.
The 2018-2019 Infiniti Q50 specifications note a socket requirement alongside the 158 bulb size, indicating that the bulb is supplied or installed as part of a socket assembly for those years.
The 2021-2024 model years carry no socket notation in the specifications, suggesting the fitment configuration for those years differs from the 2018-2019 entries.
