Additional Notes

The PC74 is the sole instrument panel bulb type listed across all model years of the Toyota MR2 Spyder covered by these specifications, spanning 2000-2005.
The PC74 operates at 12 volts and draws 1.4 watts, placing it in the low-wattage category typical of instrument cluster illumination where heat management and longevity are priorities.
This bulb follows the T5 wedge form factor, which refers to a tubular glass envelope approximately 5/8 inch wide, a size standard to many instrument panel applications.
The PC74 uses a printed circuit board twist-lock socket rather than a conventional push-in or bayonet base, meaning it is not interchangeable with standard T5 wedge bulbs that lack the twist-lock feature.
The PC74 carries ANSI standardization recognized in both the United States and Canada, indicating the bulb conforms to a defined specification rather than being a proprietary part exclusive to one manufacturer.
The twist-lock socket design is specific to instrument clusters that use printed circuit boards as the wiring substrate, a construction method that routes electrical traces directly through the board rather than through discrete wiring harnesses.
