Additional Notes

The Pontiac Firebird license plate position uses three distinct bulb types across its production span: the 194, the 97, and the 67.
The 194 is a T10 miniature wedge bulb rated at 12V and 3.78W, conforming to ANSI standards for the US and Canadian markets. Its wedge base design requires no separate metal base, as the glass envelope itself acts as the retention mechanism within the socket.
The 97 and 67 both use a BA15s single-contact bayonet base, which is the same base type found on the widely recognized 1156 bulb. The bayonet mount is secured by twisting the bulb into the socket rather than pushing it straight in.
The 97 is rated at 12V and 13W, making it a higher-wattage variant within the BA15s bayonet family compared to the 67, which is rated at 12V and 8W.
Although the 97 and 67 share the same BA15s bayonet base as the 1156, they are lower-wattage variants of that bulb type and are not electrically interchangeable with it without consideration of the wattage difference.
The Pontiac Firebird used the 194 wedge bulb for the license plate position across the 1974-1997 model years, representing the longest continuous fitment period in the specifications.
The 97 bulb applies specifically to the 1971-1973 Firebird, occupying a transitional position between the earlier 67 fitment and the later adoption of the 194.
The 67 bulb was fitted to the 1967-1970 Firebird for the license plate position. Despite sharing the BA15s base with the 97, the two bulbs are not wattage-equivalent and serve different model year ranges.
The shift from the BA15s bayonet-based bulbs to the T10 wedge-based 194 between the 1973 and 1974 model years reflects a socket design change at the license plate position.
All three bulb types in these specifications conform to ANSI standards recognized in both the United States and Canada.
