Nissan Rogue Back Up Light Bulb Size

Additional Notes

• The Nissan Rogue backup light uses the 921 bulb across the 2008-2023 model years covered in these specifications, with the single exception of 2021 and 2022, which are not listed.
• The 921 is classified as a T15 wedge bulb under the ANSI standardization system recognized in both the United States and Canada.
• The 921 bulb operates at 12 volts and draws 16 watts, which is consistent with standard automotive incandescent backup light applications.
• The T15 designation refers to the bulb's tubular shape, with the numeric portion indicating a width of 15 eighths of an inch across the glass envelope.
• The wedge base design means the 921 is held in its socket by the tension of the base itself rather than by a separate locking mechanism such as a bayonet or screw fitting.
• Because the 921 is an ANSI-standardized type, it is produced by multiple manufacturers and is considered a widely interchangeable part within that standard.
• The 921 shares its wedge base and voltage rating with several related bulb types, such as the 912 and 906, but those alternatives carry different wattage ratings and are not direct drop-in replacements without verifying socket and circuit compatibility.
