Additional Notes

The bulb size 67 is an ANSI-standardized type recognized in both the United States and Canada, operating at 12 volts and 8 watts.
The 67 bulb uses a BA15s bayonet base, which is a single-contact base design that indexes the bulb in one rotational position during installation.
As a single-filament bulb, the 67 type serves functions that require only one lighting mode, such as license plate illumination.
The 67 is a lower wattage variant of the 1156 bulb, sharing the same BA15s base but drawing less power, which means the two types are not directly interchangeable despite their physical similarities.
The Peterbilt 365 uses the 67 bulb for the license plate position across the 2008-2009 model years covered in these specifications.
