Additional Notes

The bulb size 37 is an ANSI-standardized miniature wedge type with a T5 form factor, rated at 12 volts and 1 watt, placing it among the lower-wattage bulbs used in interior vanity mirror lighting applications.
The T5 wedge base design means the bulb is held in place by the tension of its base contacts rather than a bayonet or screw mechanism, which is a common trait of small interior lighting components.
The INFINITI Q50 uses the size 37 bulb for the sun visor position across the 2021-2023 model years, indicating consistent fitment within that production span.
The size 37 designation follows ANSI standardization recognized in both the United States and Canada, meaning the bulb specification is not region-specific within those markets.
At 1 watt, the size 37 bulb draws minimal current, which is typical for vanity mirror illumination where sustained low-level light output is the functional requirement rather than high brightness.
