Additional Notes

The Isuzu NQR uses the 1156 bulb for its back up light across all Tilt Cab configurations from 1996 to 2013.
The 1156 is an ANSI-standardized bulb type, meaning its physical and electrical specifications conform to a defined industry standard recognized in the United States and Canada.
This bulb operates on a 12-volt electrical system and draws 21 watts, which is typical of incandescent automotive reverse lighting applications.
The 1156 uses a BA15s bayonet base, which is a single-contact bayonet mount. The "s" in BA15s denotes a single center contact at the base, as opposed to the dual-contact BA15d found on two-filament bulbs.
Because the 1156 is a single-filament bulb, it serves only one lighting function per socket, which is consistent with its use in a dedicated back up light position.
The BA15s base type is not interchangeable with the BA15d base. Substituting a dual-contact bulb in a single-contact socket would result in improper fitment.
The Tilt Cab body style designation applies to every model year listed in the specifications, indicating this fitment is specific to that cab configuration of the NQR.
