Additional Notes

The Jeep CJ5 license plate bulb specifications cover two distinct bulb types across the model's production years: the 97 and the 89.
Both the 97 and 89 are ANSI-standardized bulbs recognized in the US and Canada, each operating at 12 volts and rated at 13 watts.
Both bulb types use a BA15s bayonet base, a single-contact base design that secures the bulb with a twist-lock motion rather than a threaded socket.
Both the 97 and the 89 are single-filament bulbs, meaning each serves a single lighting function rather than switching between two brightness levels.
Both bulbs are described as variants of the 1156, a widely used automotive bulb, with the 89 specifically noted as a lower wattage variant of that type.
The Jeep CJ5 uses the 97 bulb for the license plate position across the 1974-1983 model years.
The 89 bulb applies to the license plate position on the CJ5 for the 1959-1968 model years.
Although the 97 and 89 share the same BA15s base type, they are distinct part numbers and are not confirmed as interchangeable within these specifications.
