Additional Notes

The ANSI 67 bulb is the most frequently specified license plate bulb for the Fiat Brava, covering the 1978-1979 and 1981 model years.
The ANSI 89 bulb is specified exclusively for the 1980 Fiat Brava license plate position.
Both the 67 and 89 are ANSI-standard bulbs recognized in the US and Canadian markets.
Each bulb type uses a BA15s bayonet base, meaning the two types share the same base configuration despite differing in wattage.
The BA15s designation refers to a single-contact bayonet base with a 15mm collar, a common format in automotive lighting applications.
The 67 bulb operates at 12V and 8W, while the 89 bulb operates at 12V and 13W, making the 89 a notably higher-output variant for the same base type.
Both bulbs are described as lower wattage variants of the 1156, which itself is a widely used single-filament BA15s automotive bulb rated at 12V and approximately 27W.
Because the 67 and 89 share a BA15s base, physical fitment in the socket is possible for either type, though the wattage difference means they are not rated equivalents and direct substitution may affect output.
