Additional Notes

The Chevrolet C60 uses the 67 bulb for its license plate position across all listed model years from 1979-1988.
The 67 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a standardized North American specification framework.
This bulb operates on a single-filament design, meaning it serves one lighting function rather than switching between two output levels as a dual-filament bulb would.
The 67 bulb uses a BA15s bayonet base, a single-contact mount where the bulb locks into its socket with a twist, distinguished from double-contact bayonet variants by its single pin alignment.
At 12 volts and 8 watts, the 67 bulb draws relatively low current, consistent with the low-intensity output expected of a license plate illumination source.
The 67 bulb is a lower wattage variant of the 1156, which shares the same BA15s base type but operates at a higher wattage. The two bulbs are not interchangeable despite the shared base, as the difference in wattage affects output and socket compatibility in specific applications.
