Additional Notes

The Toyota Avalon glove box uses two bulb types across its model years: the 74 and the 37, both of which are ANSI-standard miniature wedge bulbs rated at T5 and operating on 12 volts.
The primary distinction between the two bulbs is wattage. The 74 draws 1.4W, while the 37 draws 1W, making them electrically incompatible substitutes for one another despite sharing the same T5 wedge form factor.
The 74 bulb is specified for the Toyota Avalon glove box across the 1995-1997 model years, then again from 2005-2012, representing the more widely used of the two bulb types across this vehicle's history.
The 37 bulb is specified for the 1998-2004 model years, covering a continuous seven-year span in the middle of the production range covered by these specifications.
The T5 designation refers to the bulb's tubular glass envelope, which is five-eighths of an inch wide. This is a compact form factor commonly found in low-wattage interior lighting applications such as glove boxes and instrument panels.
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. This construction is standard for low-current interior bulbs.
Although the 74 and 37 share the same T5 wedge base, the difference in wattage means a direct substitution between the two could result in incorrect illumination output or potential electrical stress on the socket circuit.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances recognized across North American automotive applications.
