Additional Notes

The PC74 is the parking brake indicator bulb size for the Chevrolet Silverado across the 1999-2002 model years.
The PC74 is an ANSI-standard bulb recognized in both the United States and Canada, classifying it as a North American market specification.
The PC74 belongs to the T5 bulb family, which refers to a tubular miniature wedge form factor approximately 5/8 of an inch wide at its widest point.
Unlike standard wedge bulbs that use friction-fit sockets, the PC74 uses a printed circuit board twist-lock socket, meaning it is designed specifically for direct integration into instrument cluster circuit boards rather than conventional wiring harnesses.
The PC74 operates at 12 volts and draws 1.4 watts, placing it among the lower-wattage miniature bulbs used in automotive instrument panel applications.
The twist-lock socket type of the PC74 is not interchangeable with standard wedge-base T5 bulbs, even though both share the same general T5 form factor, as the mounting and retention mechanisms differ between the two socket types.
