Additional Notes

The Nissan NV2500 uses the 921 bulb for the back up light position across the 2012-2021 model years.
The 921 is a T15 wedge-base bulb, meaning it uses a plastic wedge at its base rather than a metal pin or bayonet fitting to secure it in the socket.
The 921 bulb operates at 12 volts and draws 16 watts, which is consistent with standard automotive electrical systems.
The 921 designation follows the ANSI standard, which is the classification system used in the United States and Canada for automotive bulbs.
The T15 designation refers to the tubular shape of the bulb envelope, with the number indicating its width in eighths of an inch, placing it in a relatively compact size category for wedge bulbs.
Because the 921 is an ANSI-standardized bulb type, it is produced by multiple manufacturers, and any 921-rated bulb meeting the T15 wedge form factor at 12V and 16W is considered a direct fit for this application.
Wedge-base bulbs such as the 921 are not interchangeable with bayonet-base or pin-base bulb types, even when wattage or voltage ratings are similar.
