Additional Notes

The bulb size 89 is an ANSI-standard single-filament bulb rated at 12 volts and 13 watts, fitted with a BA15s bayonet base. It is a lower-wattage variant of the more common 1156 bulb.
The BA15s bayonet base designation indicates a single-contact base with a 15mm collar, which is a widely used base type in automotive interior and exterior lighting applications.
The INFINITI I30 uses the 89 bulb for the map light across the 1998-2001 model years, though this fitment applies specifically to vehicles without a sunroof.
The 1998 model year carries an additional qualifier noting fitment from 02/1998, meaning this specification applies to units produced from February 1998 onward within that model year.
The 2000 and 1999 model years include a "Front" qualifier in their specifications, indicating the 89 bulb applies to the front map light position in those years.
Because the 89 bulb is a lower-wattage variant of the 1156, the two are not directly interchangeable despite sharing the BA15s base, as the wattage and light output differ between them.
