Additional Notes

The Chevrolet Cruze brake bulb specifications cover the 2011-2018 model years, with two distinct bulb types used across that span.
The 3057 bulb is specified for the 2011-2015 Chevrolet Cruze, making it the fitment used across the majority of the covered model years.
The 7443 bulb replaced the 3057 starting with the 2016 Cruze and carries through the 2016-2018 model years.
Both the 3057 and 7443 are dual-filament wedge bulbs operating on a 12V system, with the dual-filament design serving separate brightness levels for braking and running light functions.
The 3057 is a T25 wedge bulb rated at 27W on its high-intensity filament and 7W on its low-intensity filament, giving it higher wattage output than the 7443.
The 7443 is a T20 wedge bulb rated at 21W and 5W respectively, making it physically smaller in base size than the 3057 despite sharing the same general wedge construction.
Both bulbs conform to ANSI standards applicable in the US and Canada, meaning they meet the same regulatory framework but are not interchangeable with each other due to differences in base size and wattage.
The T20 and T25 designations refer to the base width of each bulb type, and because these widths differ, a 7443 will not seat correctly in a socket designed for the 3057, and vice versa.
