The Chevrolet Aveo side marker requires a 168 bulb size for proper installation and function within the lighting assembly. Data for the specified component covers the range from 2008 to 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Aveo uses three distinct bulb types across its front and rear side marker positions: the 2357NA, the 1157, and the 12961.
The 2357NA and 1157 are both ANSI-standardized bulbs for the US and Canadian markets, and both share the BAY15d bayonet base with dual-filament construction operating at 12V.
Despite sharing the same BAY15d base, the 2357NA and 1157 are not interchangeable. The 2357NA draws 26.9W on its primary filament and 8W on its secondary, while the 1157 draws 21W and 5W respectively.
The 2357NA carries natural amber glass, which produces its amber output through the glass itself rather than through a lens or housing, distinguishing it from clear-glass alternatives in the same family.
The 12961 is a Philips part number designation for a miniature wedge-style T10 bulb with a W2.1x9.5d base, operating at 12V and 5W. Its single-filament wedge construction is physically incompatible with the BAY15d sockets used by the 2357NA and 1157.
The Chevrolet Aveo (2009-2011) uses the 2357NA for the front side marker position, while the same model years use the 1157 for the rear side marker position.
The Chevrolet Aveo (2007-2008) uses the 12961 in both the front and rear side marker positions, making it the only configuration in these specifications where a single bulb type serves both locations on the vehicle.
The wattage difference between the 12961 at 5W and the dual-filament bulbs at up to 26.9W reflects a significant difference in socket type, pin configuration, and intended circuit load, reinforcing that these bulb families are not cross-compatible.
