Additional Notes

The Ford Maverick uses the ANSI 89 bulb for trunk lighting across the 1973-1977 model years.
The 89 bulb operates on a 12-volt electrical system and draws 13 watts.
It is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as stop and tail.
The 89 uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm collar.
The 89 is classified as a lower wattage variant of the 1156 bulb, which shares the same BA15s base type but operates at a higher wattage.
Because the 89 and 1156 share the same base, physical fitment of a 1156 into a BA15s socket is possible, though the wattage difference means the two are not direct electrical equivalents.
The 89 bulb is standardized under ANSI specifications and is recognized in both the United States and Canada.
