Additional Notes

The T5 miniature wedge bulb, designated as ANSI type 37, is the sun visor bulb used in the Infiniti QX80 across the 2021-2023 model years. It operates at 12 volts and draws 1 watt of power.
The T5 designation refers to the bulb's tubular glass envelope, which is 5/8 of an inch wide. This compact form factor is standard for low-output interior lighting applications such as vanity mirrors and sun visor lamps.
At 1 watt, the type 37 bulb produces a low level of illumination suited to close-range tasks. Its minimal power draw places very little load on a vehicle's electrical system.
The ANSI type 37 designation indicates the bulb conforms to standards recognized in both the United States and Canada, meaning replacements sourced from either market are electrically and physically equivalent.
The wedge base design of the type 37 bulb means it is held in its socket by the tension of the base contacts rather than by a bayonet or screw mechanism. Removal involves pulling the bulb straight out from the socket.
Because the type 37 shares the T5 wedge base with several other low-wattage bulb types, substitution with a visually similar bulb of a different wattage rating is not advisable, as the socket is matched to the 1-watt specification.
