Additional Notes

The T5 miniature wedge bulb, designated as type 74 under the ANSI standard recognized in the US and Canada, is the specified courtesy bulb for the Nissan GT-R across the 2021-2024 model years (excluding 2022).
The type 74 bulb operates at 12 volts with a power draw of 1.4 watts, placing it among the lower-wattage bulbs used in automotive interior applications.
The T5 designation refers to the bulb's tubular envelope, with the numeral indicating a width of 5/8 inch. This form factor is common in instrument panel and courtesy lighting positions where space is limited.
The wedge base design of the type 74 eliminates the need for a separate metal base or bayonet pins, as the glass envelope itself acts as the retention mechanism within the socket.
Substitution with bulbs outside the T5 wedge category risks physical incompatibility with the socket housing, even if voltage ratings are similar.
