Additional Notes

The Jeep CJ7 uses the 97 bulb for its license plate light across all available model years in the specifications, spanning 1976-1986.
The 97 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It operates on a 12-volt electrical system and draws 13 watts, which is consistent with standard automotive low-current lighting applications.
The 97 bulb uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin rather than the dual-pin BA15d configuration.
The 97 is a single-filament bulb, meaning it serves one lighting function only, as opposed to dual-filament types that handle two functions such as running and brake light duties.
The 97 bulb is a variant of the more widely known 1156, sharing the same BA15s bayonet base but differing in wattage, which makes the two types not directly interchangeable in all applications.
