The Chevrolet Traverse tail light requires a 7443 bulb size for proper installation and function within the rear lighting assembly. Data provided for the specific component covers the range from 2009 to 2018.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Traverse outer tail light uses the 7443 bulb across the 2009-2018 model years.
The 7443 is a dual-filament wedge bulb operating at 12V with a wattage rating of 21W for the primary filament and 5W for the secondary filament, conforming to the T20 wedge form factor under the ANSI standard for the US and Canada markets.
The dual-filament design of the 7443 allows a single bulb to serve two lighting functions simultaneously, typically combining stop and tail light operation within one housing.
The Chevrolet Traverse (2013-2016) inner tail light position uses the 168 bulb size.
The 168 is a miniature wedge bulb in the T10 form factor, rated at 12V and 4.9W, also conforming to the ANSI standard for the US and Canada markets.
The 168 and 7443 are both wedge-base bulbs but are not interchangeable, as they differ in physical size, wattage, and filament configuration.
The outer tail light position on the 2013-2016 Traverse shares the same 7443 specification as the broader 2009-2018 outer tail light fitment, meaning both sub-part entries align for those overlapping years.
The T10 form factor of the 168 bulb is significantly smaller than the T20 form factor of the 7443, making socket compatibility between the two positions mechanically distinct.
