The Chevrolet Cruze side marker requires a bulb with a 168 size specification for proper installation and function within the lighting assembly. Data for the specific component covers the period from 2016 through 2018.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 194 bulb is an ANSI-standard miniature wedge type, classified under the T10 form factor, and operates at 12V with a power draw of 3.78W. Its low wattage places it in the category of small indicator and marker lamps rather than primary lighting.
The 7443 bulb is an ANSI-standard dual-filament wedge type, classified under the T20 form factor, and operates at 12V with a dual-wattage rating of 21W and 5W. The two filaments allow a single bulb to serve both a brighter active function and a dimmer standing-light function within the same housing.
The front side marker on the Chevrolet Cruze uses the 194 bulb across all model years from 2011-2018, making it consistent throughout the entire production span covered by these specifications.
For the 2016-2018 Cruze front side marker, the 194 bulb size applies specifically to vehicles without projector-type headlamps, indicating that the headlamp configuration on those model years is a relevant factor in bulb fitment.
The rear side marker on the 2011-2015 Cruze uses the 194 bulb, while the 2016-2018 Cruze rear side marker uses the 7443 bulb, representing a change in rear marker lamp specification between those production periods.
The 7443 dual-filament T20 bulb used in the 2016-2018 rear side marker position is not interchangeable with the single-filament 194 T10 bulb used in earlier model years, as the two differ in filament count, physical size, wattage, and connector type.
Both the 194 and 7443 bulbs conform to ANSI standards recognized in both the United States and Canada, placing them within a shared North American specification framework.
