Additional Notes

The Nissan Armada uses the 921 bulb size for the back up light across all listed model years from 2005 to 2020.
The 921 is classified as a wedge-type bulb, designated T15, which refers to its tubular shape and the wedge base that holds it in place without a separate socket locking mechanism.
The 921 bulb operates at 12 volts and draws 16 watts, which is consistent with standard automotive reverse lighting applications.
The 921 designation follows the ANSI standard, meaning it is a recognized specification in both the United States and Canada.
The T15 wedge base format means the bulb is held by friction through its plastic wedge base rather than by a bayonet or screw-type fitting, which is a relevant detail for installation and removal.
Because the 921 is an ANSI-standardized bulb, it is produced by multiple manufacturers, and any 921-rated T15 wedge bulb meeting the 12V, 16W specification is considered a compatible replacement for the Nissan Armada (2005-2020) back up light position.
The 2016 model year is not present in the listed specifications, so no bulb size data for that year is reflected here.
