Additional Notes

The Toyota Tundra glove box uses two bulb sizes across its model years: the 74 and the 37, both of which are ANSI-standard miniature wedge bulbs of the T5 form factor operating at 12 volts.
The bulb 74 is rated at 1.4W, while the bulb 37 is rated at 1W. Although both share the same T5 wedge form factor and voltage, the wattage difference means the two types are not interchangeable.
The Toyota Tundra (2007-2021) uses the 74 bulb for the glove box, with the exception of the years 2014-2017, which are not represented in the specifications.
The 2004 Tundra also uses the 74 bulb, while the 2000-2003 and 2005-2006 model years use the 37 bulb instead.
The T5 designation refers to the tubular envelope width of the bulb, expressed in eighths of an inch, making a T5 bulb five-eighths of an inch wide. This is a widely used size in low-wattage interior lighting applications.
The wedge base design on both bulb types means the bulb is held in its socket by the tension of the base contacts rather than by a separate bayonet or screw mechanism, which is a common construction for small interior bulbs.
