The Kia Rio5 turn signal requires a 1156NA bulb size for the specific lighting components located on the front or rear of the vehicle. Data for the specified bulb requirements covers the range from 2007 to 2008.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1156NA is the most frequently specified bulb across the Kia Rio5 turn signal data, appearing in the front position for 2006-2009 and in the rear position for all six model years covered, 2006-2011.
The 1156NA is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base. The BA15s designation indicates a single-contact base with a 15mm collar, which accepts only single-filament bulbs and is not interchangeable with dual-filament bases.
The 2357NA appears exclusively in the front turn signal position of the Kia Rio5 for the 2010-2011 model years, representing a specification change from the 1156NA used in earlier model years.
The 2357NA is a dual-filament bulb rated at 12V with a high filament draw of 26.9W and a low filament draw of 8W. It uses a BAY15d bayonet base, where the "d" suffix indicates an offset dual-contact pin arrangement that physically prevents incorrect single-filament bulb installation.
Both the 1156NA and 2357NA carry the "NA" suffix, which denotes natural amber glass rather than a clear envelope. This coloring is built into the glass itself and produces the amber signal output without relying on a colored lens.
Because the BA15s and BAY15d bases are mechanically distinct, the 1156NA and 2357NA are not interchangeable. Installing a 1156NA in a socket designed for the 2357NA, or vice versa, is not possible without modification due to the differing pin configurations.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized electrical and photometric performance within those markets.
The rear turn signal position uses the 1156NA uniformly across all six model years in the specification, meaning the rear socket retains the BA15s single-contact base throughout the entire 2006-2011 production span covered.
