Additional Notes

The 158 bulb is an ANSI-standardized miniature wedge type, classified under the T10 form factor, and operates at 12 volts with a 3-watt output. It is the sole bulb size listed across all glove box specifications for the INFINITI QX50.
The 2019 and 2017 model years specify the 158 bulb with a socket included, while the 2022 model year lists the 158 bulb without that notation, indicating a potential difference in how the replacement part is supplied or installed between these years.
The T10 wedge base is a common automotive miniature bulb format, meaning the 158 fits into a wedge-style socket rather than a bayonet or screw base. This base type is widely used in low-current interior lighting applications.
At 3 watts and 12 volts, the 158 draws a relatively low current, consistent with its role in illuminating a small interior compartment rather than a high-output exterior lighting position.
