Additional Notes

The Jeep Patriot uses the 921 bulb size for the back up light across all model years covered in the specifications, spanning 2007-2017.
The 921 is a wedge-type bulb, classified under the T15 designation, which refers to its tubular shape with a width of 15 eighths of an inch.
Wedge bulbs use a wedge-shaped base that is held in place by tension within the socket, rather than by a bayonet or screw mechanism.
The 921 operates at 12 volts and 16 watts, which is consistent with standard automotive electrical systems.
The 921 conforms to ANSI standards and is recognized in both the United States and Canada, indicating a standardized specification shared across North American markets.
Because the 921 is an ANSI-standardized bulb, it is produced by multiple manufacturers, and units from different brands are generally interchangeable as long as the T15 wedge base and 12V/16W ratings are matched.
The consistent use of a single bulb type across all eleven model years of the Jeep Patriot means that back up light bulb fitment does not vary by year within this vehicle.
