Additional Notes

The Honda CR-Z parking light specifications reference two bulb types across the 2011-2016 model years: the 7443NA and the 7444NA.
Both the 7443NA and 7444NA are ANSI-standardized bulbs, meaning they conform to a defined set of electrical and physical criteria recognized in the United States and Canada.
Each bulb is a dual-filament wedge type in the T20 form factor, which allows a single bulb to serve two brightness levels within one housing.
Both bulbs operate at 12 volts and carry a 21W/5W power rating, where the higher wattage filament serves the brighter function and the lower wattage filament serves the reduced-intensity function.
The natural amber glass designation on both bulbs means the color is produced by the glass envelope itself rather than by a coating or the vehicle's lens, which tends to produce a more consistent amber output over the bulb's service life.
The Honda CR-Z (2012-2013 and 2015-2016) uses the 7443NA, while the 2011 and 2014 model years use the 7444NA.
Although the 7443NA and 7444NA share the same voltage, wattage, glass type, and T20 wedge form factor, they carry distinct ANSI part numbers, and the specifications treat them as separate fitments rather than interchangeable units.
