Additional Notes

The Isuzu FVR uses the 1156 bulb across all listed model years for the back up light position, spanning from 1988 to 2011.
The 1156 is an ANSI-standardized bulb type recognized across the United States and Canada, ensuring broad availability in those markets.
The 1156 bulb operates on a 12-volt electrical system and draws 21 watts, which is typical for single-filament incandescent automotive bulbs used in signaling and reversing applications.
The 1156 uses a BA15s bayonet base, a single-contact fitting where the "s" denotes a single pin, as opposed to the dual-contact BA15d variant. These two base types are not interchangeable.
Being a single-filament bulb, the 1156 serves one lighting function only, distinguishing it from dual-filament types such as the 1157, which handles two functions from a single housing.
Model years 2002-2011 carry a Tilt Cab designation in the specifications, indicating that the 1156 fitment applies specifically to that cab configuration for those years.
Model years 1988-1995 carry a Heavy Duty designation, indicating the 1156 fitment is specified for that variant of the Isuzu FVR during that period.
Model years 1996-2001 carry no sub-model designation in the specifications, with the 1156 listed without a cab or duty qualifier for those years.
