Additional Notes

The Pontiac Bonneville uses the 194 bulb for its license plate across the widest span of model years in these specifications, covering 1974-1999 with the exception of 1977, which takes the 168 bulb instead.
Both the 194 and 168 are T10 miniature wedge bulbs operating at 12V, though they differ in wattage. The 194 draws 3.78W while the 168 draws 4.9W, making them physically similar but not electrically identical.
The 1977 Bonneville is the only model year within the 1974-1999 range that specifies the 168 bulb rather than the 194, which means substituting one for the other without accounting for the wattage difference is a relevant fitment consideration.
Model years 1971-1973 use the 97 bulb, a single-filament BA15s bayonet-base bulb rated at 12V and 13W. It is classified as a variant of the 1156 family.
The 67 bulb is specified for the Bonneville across 1957-1970, excluding 1964. It also uses a BA15s bayonet base and operates at 12V, but at a lower 8W output compared to the 97.
Although the 67 and 97 share the same BA15s bayonet base type, their wattage ratings differ significantly at 8W and 13W respectively, which is a relevant distinction when considering interchangeability between those model year groups.
The 1964 Bonneville stands apart from all surrounding model years by specifying the 1155 bulb, a BA15s bayonet-base bulb rated at 12V and 21W, making it the highest-wattage license plate bulb in these specifications.
All five bulb types listed across these specifications conform to ANSI standards recognized in both the United States and Canada.
