Additional Notes

The T5 miniature wedge bulb, designated as ANSI type 37, operates at 12 volts and draws 1 watt, placing it in the low-power end of automotive interior lighting.
The T5 designation refers to the bulb's tubular form factor, with the numeric suffix indicating a width of five-eighths of an inch across the envelope.
The wedge base design means the bulb is held in its socket by the tension of the base contacts alone, with no separate metal cap or bayonet pins involved in retention.
The ANSI type 37 standard applies across both the United States and Canada, meaning the specification is consistent for North American market vehicles.
The Infiniti QX55 uses the type 37 bulb for the sun visor position across the 2022-2023 model years.
