Additional Notes

The 1156NA is the specified rear turn signal bulb for the Kia Soul EV across the 2015-2019 model years.
The 1156NA follows the ANSI standardization system, which establishes uniform electrical and mechanical specifications for bulbs used in the United States and Canada.
This bulb operates on a single-filament design, meaning it serves one lighting function only, as opposed to dual-filament bulbs that handle two functions such as braking and turn signaling simultaneously.
The BA15s bayonet base is a single-contact bayonet mount, and the "s" designation specifically indicates a single contact at the base, which is not interchangeable with the BA15d double-contact variant.
The natural amber glass of the 1156NA produces its amber output through the glass coating itself rather than through a clear bulb paired with an amber lens, which affects color output when used in housings of different tints.
The bulb is rated at 12 volts and 21 watts, which are standard values for automotive turn signal applications in this class of vehicle.
Because the 1156NA carries a natural amber glass coating, substituting it with a standard clear 1156 bulb of otherwise identical construction would alter the color output at the lens.
