Additional Notes

The Kia Spectra tail light specifications cover model years 2000-2001 and 2005-2009, with two distinct bulb types appearing across those years.
The 1157 is the more frequently specified bulb, appearing in the 2000-2001 and 2007-2009 model years.
Both the 1157 and 2357 are ANSI-standardized dual-filament bulbs operating on a 12-volt system with a BAY15d bayonet base.
The dual-filament design of both bulb types allows a single bulb to serve two functions, typically combining stop light and tail light operation within one housing.
The BAY15d bayonet base features two offset pins, a physical characteristic that ensures correct polarity alignment during installation.
The 1157 operates at 21W on its high filament and 5W on its low filament, while the 2357 operates at 26.9W and 8W respectively.
The 2357 is a higher-wattage variant of the 1157 and produces greater light output across both filaments.
The 2005-2006 Kia Spectra uses the 2357 bulb, which draws more current than the 1157 used in adjacent model years.
Although the 1157 and 2357 share the same BAY15d base and are physically interchangeable in many fixtures, substituting one for the other in the Spectra may result in output levels that differ from the original specification.
