Additional Notes

The Peterbilt 353 uses two different license plate bulb sizes across the 1986-1988 model years: the 67 and the 97, with the applicable size depending on the headlamp configuration of the vehicle.
Both the 67 and 97 are ANSI-standardized bulbs recognized in the US and Canada, each featuring a single filament and a BA15s bayonet base.
The BA15s bayonet base is a single-contact bayonet fitting, distinguishable from the dual-contact BA15d base by its single pin on the base collar.
The 67 bulb operates at 12V and 8W, while the 97 bulb operates at 12V and 13W, meaning the two bulbs draw different amounts of power despite sharing the same base type.
Both bulbs are variants of the 1156, a widely used automotive bulb, though they differ from it in wattage output.
The 97 bulb applies specifically to the Peterbilt 353 equipped with Halogen Capsule Headlamps, making headlamp type a determining factor in the correct license plate bulb selection.
The 67 bulb applies to units without the Halogen Capsule Headlamp configuration across all three model years covered in the specifications.
Although the 67 and 97 share the same BA15s base, their wattage difference means they are not interchangeable without affecting the electrical load at the license plate lamp socket.
