Additional Notes

The ANSI 89 bulb is the sole engine compartment light bulb size listed for the Ford Maverick across the 1973-1976 model years.
The 89 bulb follows the ANSI standard, meaning it conforms to a specification recognized in both the United States and Canada.
It is a single-filament bulb, indicating 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. The "s" in BA15s denotes a single contact point at the base, as opposed to the dual-contact BA15d.
The bulb operates at 12 volts and draws 13 watts, placing it in the lower output range typical of utility and underhood lighting applications.
The 89 is described as a lower wattage variant of the 1156 bulb. While both share the BA15s bayonet base, they are not interchangeable in all applications due to the wattage difference, and substituting a higher-wattage 1156 in a socket rated for the 89 may exceed the circuit's intended load.
