Additional Notes

The ANSI 67 bulb is the specified license plate bulb for the Ferrari 348 GTB across the 1993-1994 model years.
The 67 bulb operates on a 12-volt electrical system and draws 8 watts, placing it in the lower-wattage category of the BA15s bayonet base family.
The BA15s designation indicates a single-contact bayonet base, which means the bulb has one electrical contact pin at the bottom and a single filament.
The 67 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 parameters shared across compliant manufacturers.
The 67 is a lower-wattage variant of the 1156 bulb. Both share the BA15s bayonet base, but the 1156 operates at a higher wattage, making the two types electrically non-equivalent despite their physical similarities.
The shared BA15s base between the 67 and the 1156 means the 1156 can physically seat into the same socket, but the wattage difference represents a fitment incompatibility for applications specifying the 67.
