Additional Notes

The bulb size 37 is an ANSI-standardized miniature wedge type, classified under the T5 form factor, and operates at 12 volts with a power draw of 1 watt. Its low wattage reflects its role in low-intensity interior lighting applications such as sun visor illumination.
The Infiniti QX50 uses the size 37 bulb for the sun visor across the 2021-2023 model years. All three years share the same specification, meaning a single bulb type serves the full span of this production range without variation.
The T5 designation refers to the bulb's tubular envelope width, expressed in eighths of an inch, placing it among the smaller miniature bulb formats used in automotive interiors. The wedge base type requires no separate socket retainer, as the base itself is held by tension within the housing.
Because the size 37 bulb is an ANSI-recognized standard applicable in both the United States and Canada, replacement units sourced from either market are electrically and physically equivalent for this application.
