Additional Notes

The Isuzu NQR uses the 89 bulb size for the license plate position across all listed model years, spanning 1996-2013.
The 89 bulb is an ANSI-standardized type recognized in both the United States and Canada, operating at 12 volts and 13 watts.
The 89 bulb uses a BA15s bayonet base, which is a single-contact base type that locks into its socket with a twist-and-push motion.
As a single-filament bulb, the 89 type serves one lighting function only, which is consistent with its application in a license plate position.
The 89 bulb is a lower-wattage variant of the 1156, meaning the two types share the same BA15s base but are not interchangeable due to the difference in wattage output.
Substituting a 1156 for an 89 in the Isuzu NQR license plate socket carries a risk of electrical incompatibility, as the higher wattage of the 1156 exceeds the rating associated with the 89 position.
The Tilt Cab body configuration is specified across all listed model years, indicating this fitment applies specifically to that cab style of the NQR.
