Additional Notes

The Toyota 4Runner glove box uses two bulb sizes across its model years: the 37 and the 74, both of which are ANSI-standard miniature wedge bulbs of the T5 type rated at 12 volts.
The bulb 37 draws 1 watt, while the bulb 74 draws 1.4 watts. Although both share the same T5 wedge form factor and voltage rating, the difference in wattage means they are not interchangeable without affecting electrical load.
The Toyota 4Runner (2003-2009) uses the 37 bulb for the glove box.
The 74 bulb is specified for the glove box across the 1984-2002 model years, representing the longer-running fitment of the two bulb sizes in this application.
The T5 designation refers to the tubular glass envelope width, which in the imperial system equals five-eighths of an inch. This is a widely used size in low-wattage interior lighting applications.
The wedge base design on both bulbs means the base itself acts as the contact point, with no separate metal shell or bayonet pins. This construction is common in compact interior lamp sockets.
Both bulbs conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances across manufacturers producing these part numbers.
