The Chevrolet Equinox parking light utilizes bulb sizes 7444NA, 7443NA, and 168 depending on the specific version of the vehicle. Available data covers a range from 2005 to 2020.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The front parking light specifications for the Chevrolet Equinox span model years 2005 through 2021, drawing from three distinct bulb types: the 168, the 7443NA, and the 7444NA, with the 7440NA appearing in the 2021 model year.
The 7443NA and 7444NA are both T20 wedge bulbs operating at 12V with a dual-filament configuration rated at 21W and 5W respectively, making them functionally similar in output and physical format.
Despite their shared T20 form factor and identical wattage ratings, the 7443NA and 7444NA are separate ANSI-designated part numbers, and substituting one for the other without confirming the specific year's requirement is not supported by the specifications.
The 7440NA, used in the 2021 Chevrolet Equinox, is a single-filament T20 wedge bulb rated at 12V and 21W, distinguishing it from the dual-filament 7443NA and 7444NA types used in earlier model years.
All three T20 variants, the 7440NA, 7443NA, and 7444NA, carry natural amber glass, which produces the amber color output directly through the glass envelope rather than relying on a colored lens housing.
The 168 bulb is a T10 miniature wedge type rated at 12V and 4.9W, representing a significantly lower wattage output compared to the T20 bulbs used in later model years.
The 168 bulb was the specified front parking light for the Equinox across the 2005-2008 model years, while the T20 family of bulbs became the standard from 2010 onward.
All bulb types listed in these specifications conform to ANSI standards applicable to the United States and Canada markets.
The years 2010-2016 and 2018-2020 predominantly use either the 7443NA or 7444NA, with the specific designation varying by individual model year rather than following a continuous pattern across that range.
The T10 and T20 designations refer to the bulb's body width in units of one-eighth of an inch, meaning the T10 measures 10 eighths and the T20 measures 20 eighths, reflecting a physical size difference between the 168 and the three T20 variants.
