Additional Notes

The 2357NA is the sole bulb type specified for the Genesis G80 front turn signal across the 2017-2019 model years.
The 2357NA is an ANSI-standardized bulb recognized in both the United States and Canada, indicating it conforms to a shared North American specification rather than a regional or proprietary standard.
The 2357NA is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, each operating at a different wattage: 26.9W for the higher-intensity filament and 8W for the lower-intensity filament.
The bulb uses a BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to prevent incorrect installation orientation.
The natural amber glass of the 2357NA produces its amber turn signal color directly from the bulb itself, rather than relying on a colored lens in the housing.
The 2357NA operates on a 12V electrical system, consistent with standard automotive low-voltage architecture.
For the 2019 Genesis G80, the 2357NA fitment is noted specifically in the context of HID headlamp-equipped vehicles, indicating that the front turn signal application is tied to a particular headlamp configuration for that year.
