Additional Notes

The Peterbilt 330 uses the bulb size 67 for its license plate across the 1995-2009 model years, making it the sole fitment for most of the vehicle's production span covered in these specifications.
The bulb 67 is an ANSI-standard single-filament bulb rated at 12V and 8W, fitted with a BA15s bayonet base. It is a lower-wattage variant of the more common 1156 bulb.
The bulb 97 is also an ANSI-standard single-filament bulb with a BA15s bayonet base, rated at 12V and 13W. It draws more power than the 67, functioning as a higher-wattage variant within the same 1156 family.
For the Peterbilt 330, the bulb 97 applies exclusively to the 1995-1997 model years, and only on vehicles equipped with Halogen Capsule Headlamps.
Both the 67 and 97 share the same BA15s bayonet base, which means they are physically interchangeable in terms of socket fitment. However, their wattage ratings differ, and the correct bulb for a given vehicle depends on its headlamp configuration.
On 1995-1997 Peterbilt 330 vehicles without Halogen Capsule Headlamps, the license plate bulb specification remains the 67, not the 97.
From 1998 onward through 2009, the specifications list only the 67, with no conditional fitment variants noted for any of those years.
