The Chevrolet Trax parking light utilizes 12961 and 7443 bulb sizes according to the provided data. Information for the specified components covers the period from 2015 through 2021.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Trax front parking light specifications reference two distinct bulb types across the model years covered: the 12961 and the 7443. These two bulbs are not interchangeable, as they differ in base type, filament configuration, and wattage.
The 12961 is a Philips part number designation for a T10 miniature wedge bulb with a W2.1x9.5d base, rated at 12V and 5W. It is a single-filament bulb intended for low-draw lighting positions.
The 7443 follows the ANSI standard used in the United States and Canada. It is a T20 dual-filament wedge bulb rated at 12V with a 21W high filament and a 5W low filament, making it suitable for positions requiring two brightness levels.
The physical size difference between the T10 (12961) and T20 (7443) wedge bases means one cannot be seated in a socket designed for the other, even though both use a wedge-style base.
For the Chevrolet Trax (2017-2020), the front parking light fitment depends on headlamp configuration. Units without projector-type headlamps use the 12961, indicating that the headlamp assembly type directly determines the correct parking light bulb.
The 2021 Trax front parking light specification lists the 12961 without any headlamp configuration qualifier, suggesting a single fitment applies across that model year.
The 2016 Trax front parking light specification lists the 7443 without any headlamp configuration qualifier, similarly indicating a single fitment for that year.
The 2015 Trax shares the 7443 front parking light bulb with the 2016 model year, both listed without conditional fitment notes.
For the 2019-2020 model years, two separate front parking light entries exist: one specifying the 12961 without projector-type headlamps, and one specifying the 7443 also without projector-type headlamps. This indicates that within those years, multiple trim or build configurations carried different socket types.
