Additional Notes

The Isuzu FSR uses the type 89 bulb for the license plate position across all listed model years, spanning 1996-2002.
All entries in the specifications carry a Tilt Cab body designation, indicating this fitment applies specifically to that cab configuration.
The type 89 is an ANSI-standardized bulb recognized in both the United States and Canada, operating at 12 volts and 13 watts.
It is a single-filament bulb, meaning it serves only one lighting function rather than switching between two brightness levels.
The type 89 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and rotated to lock into place.
The type 89 is a lower wattage variant of the 1156 bulb, and while the two share the same BA15s base, they are not directly interchangeable due to the difference in wattage output.
