The Kia Spectra front turn signal requires a 1156 or 2357NA bulb size, while the rear turn signal uses a 1156NA bulb size. The replacement chart covers vehicle production years spanning 2000 to 2009 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kia Spectra front turn signal uses two distinct bulb types depending on the model year: the 1156 for 2007-2009 and the 2357NA for 2000-2001 and 2005-2006.
The 1156 is a single-filament bulb with a BA15s bayonet base, rated at 12V and 21W, conforming to ANSI standards for the US and Canadian markets.
The 2357NA is a dual-filament bulb with a BAY15d bayonet base and natural amber glass, rated at 12V with filament wattages of 26.9W and 8W, also conforming to ANSI standards.
The BAY15d base of the 2357NA features offset pins, which physically prevents it from being interchanged with the BA15s base used by the 1156 and 1156NA bulbs.
The rear turn signal position on the Kia Spectra uses the 1156NA across all listed model years from 2000-2001 through 2007-2009.
The 1156NA shares the same BA15s bayonet base, 12V rating, and 21W output as the standard 1156, with the distinction that its glass envelope is natural amber rather than clear.
Because the 1156 and 1156NA share the same BA15s base and wattage, they are physically interchangeable, though the amber tint of the 1156NA affects the color of the emitted light.
The dual-filament design of the 2357NA allows a single bulb to serve two lighting functions simultaneously, with the higher 26.9W filament typically assigned to the turn signal function and the lower 8W filament to a secondary function such as parking light.
