Additional Notes

The Peterbilt 265 license plate bulb specifications cover model years 1988-1994, with each year listing two possible bulb sizes depending on headlamp configuration.
Both the 67 and 97 are ANSI-standard single-filament bulbs sharing the same BA15s bayonet base, which is a single-contact base with a 15mm barrel.
The standard configuration across all 1988-1994 model years uses the 67 bulb, rated at 12V and 8W.
The Peterbilt 265 equipped with Halogen Capsule Headlamps requires the 97 bulb instead, rated at 12V and 13W, making headlamp type the determining factor in bulb selection.
The 97 bulb draws approximately 63 percent more wattage than the 67, meaning the two are not interchangeable despite sharing the same BA15s base.
Both the 67 and 97 are variants of the 1156 bulb family, though they differ in wattage output and are designated as separate part numbers under ANSI standards.
The shared BA15s bayonet base between the 67 and 97 means physical installation is mechanically possible with either bulb, making headlamp configuration the critical factor in selecting the correct part.
