Additional Notes

The Toyota Corolla ignition uses the 74 bulb size across the 1998-2002 model years.
The 74 bulb is classified as a T5 miniature wedge type, a form factor defined by a wedge-shaped base that seats directly into a socket without a separate metal cap or pins.
The T5 designation refers to the bulb body width, expressed in eighths of an inch, placing the body at five-eighths of an inch wide.
The 74 bulb operates at 12 volts and draws 1.4 watts, placing it among the lower-wattage miniature bulbs used in instrument and indicator applications.
The 74 bulb conforms to ANSI standards as recognized in both the United States and Canada, meaning its physical and electrical specifications follow a standardized definition shared across those markets.
The wedge base design of the 74 bulb means fitment depends on socket size and depth; substituting a physically similar but differently rated wedge bulb risks improper seating or electrical mismatch.
