Additional Notes

The Toyota Corolla uses the 74 bulb size for the ignition light across the 1998-2002 model years.
The 74 bulb is an ANSI-standardized type recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical characteristics shared across manufacturers.
It belongs to the T5 miniature wedge family, a form factor in which the base of the bulb itself acts as the connector by wedging directly into a socket, with no separate metal base or pins.
The T5 designation refers to the bulb's tubular shape with a width of 5/8 of an inch, a sizing convention used in the ANSI miniature bulb classification system.
The 74 bulb operates at 12 volts, which is consistent with the standard electrical system voltage found in passenger vehicles.
At 1.4 watts, the 74 bulb draws a very low amount of power, a characteristic typical of instrument panel and indicator lighting rather than exterior or high-output applications.
The wedge base design of the 74 bulb means that substitution with a different base type, such as a bayonet or screw base, is not physically compatible with the Toyota Corolla's ignition light socket for these model years.
