The Kia Spectra brake light utilizes 1157 and 2357 bulb sizes for the lighting components. Data for the specific bulbs covers the period from 2000 through 2009.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kia Spectra brake light specifications reference three bulb types across its model years: the 1157, 2357, and 1156, all of which conform to ANSI standards used in the United States and Canada.
The 1157 is a dual-filament bulb rated at 12V with a 21W high filament and a 5W low filament, mounted on a BAY15d bayonet base. Its dual-filament design allows it to serve both brake and tail light functions within a single housing.
The 2357 shares the same BAY15d bayonet base as the 1157 and is also a dual-filament bulb operating at 12V, but draws 26.9W on the high filament and 8W on the low filament, producing greater output than the 1157.
Because the 1157 and 2357 share the BAY15d base, they are physically interchangeable in terms of socket fit. However, their wattage ratings differ, which is a relevant factor when substituting one for the other in brake light applications on the Kia Spectra.
The Kia Spectra uses the 2357 bulb for brake lights in the 2005-2006 model years, while the 1157 is specified for the 2007-2009 and 2000-2001 model years.
The 1156 is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base. Its single-filament construction makes it suitable only for functions requiring one brightness level, such as the center high mount stop light.
The BA15s base of the 1156 differs from the BAY15d base used by the 1157 and 2357. The two base types are not interchangeable, as their pin configurations are distinct.
The center high mount stop light on the Kia Spectra uses the 1156 bulb across the 2005-2009 model years.
