The Nissan Cube brake light utilizes a 7443 bulb size for illumination across all recorded vehicle versions within the provided technical data set. Information provided covers the specific time span from 2009 through 2014 without any additional variations or changes.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan Cube uses the 7443 bulb for its brake lights across the 2009-2014 model years.
The 7443 is a dual-filament wedge bulb in the T20 form factor, rated at 12V with a wattage split of 21W for the high-intensity filament and 5W for the low-intensity filament. This dual-filament design allows a single bulb to serve both brake and tail light functions.
The 7443 conforms to ANSI standards as recognized in the United States and Canada.
The center high mount stop light on the Nissan Cube uses the 921 bulb across the 2009-2014 model years.
The 921 is a single-filament wedge bulb in the T15 form factor, rated at 12V and 16W. Unlike the 7443, it carries only one filament, making it suited for a dedicated stop light function rather than a combined brake and tail application.
The 921 also conforms to ANSI standards as recognized in the United States and Canada.
The T20 and T15 designations refer to the outer width of the wedge base, with T20 being wider than T15. These two bulbs are not physically interchangeable due to the difference in base size.
Although both the 7443 and 921 operate on a 12V system, their wattage ratings and filament configurations differ, which means one cannot serve as a functional substitute for the other even if a physical fit were possible.
