Additional Notes

The front turn signal on the Chevrolet Aveo shifted from the 1034NA bulb type (2007-2008) to the 2357NA bulb type (2009-2011), meaning these two model year groups are not interchangeable at the front position despite both using a BAY15d bayonet base.
The 2357NA is a dual-filament bulb rated at 12V with a high/low wattage of 26.9W/8W, conforming to ANSI standards for the US and Canadian markets, and features a natural amber glass envelope that produces amber light without a separate lens filter.
The 1034NA is also a dual-filament bulb on a BAY15d bayonet base, rated at 12V with a 21W/5W output, and is noted as a variant of the widely used 1157 bulb type, though the two are not necessarily direct replacements for one another.
The rear turn signal across all Chevrolet Aveo model years covered (2007-2011) uses the 1156NA, a single-filament bulb rated at 12V and 21W with a BA15s bayonet base and natural amber glass.
The BA15s base of the 1156NA and the BAY15d base of the 2357NA and 1034NA are physically distinct; the BAY15d base has two offset pins to support dual-filament operation, while the BA15s base has a single contact pin suited to single-filament use, making these base types non-interchangeable.
All three bulb types in these specifications carry the "NA" suffix, which designates natural amber glass as the light source coloring rather than a clear bulb used with an amber-colored housing or lens.
The 2357NA and 1034NA share the same BAY15d base and both serve the front turn signal position, yet their wattage ratings differ, which can affect compatibility with the vehicle's turn signal flasher relay if substituted across model year groups.
