Kia Rio5 Parking Light Bulb Size

The Kia Rio5 parking light uses bulb size 2357NA or 168 depending on the specific version required for the vehicle. Data for the lighting components covers the range from 2006 to 2011.

Additional Notes

The Kia Rio5 parking light specifications cover model years 2006-2011 and reference two distinct bulb types: the 2357NA and the 168.
The 168 bulb is a miniature wedge type with a T10 form factor, operating at 12V and rated at 4.9W. The T10 wedge base is a self-retaining design that requires no separate locking mechanism, as the bulb body itself holds it in the socket.
The 2357NA is a dual-filament bulb with a BAY15d bayonet base, rated at 12V with two wattage ratings of 26.9W and 8W corresponding to its two filaments. The natural amber glass produces a yellow-orange light output without the use of a colored lens or filter.
The BAY15d base on the 2357NA features two offset pins at different heights, a design that prevents incorrect insertion by ensuring the bulb can only be seated in one orientation.
The Kia Rio5 (2006-2009) uses the 168 bulb for the parking light position across four consecutive model years.
The 2010-2011 Rio5 uses the 2357NA, which represents a shift to a dual-filament bulb with a bayonet base, making it physically and electrically incompatible with the T10 wedge socket used in earlier model years.
Both bulb types are defined under ANSI standards applicable in the United States and Canada, indicating standardized electrical and physical tolerances shared across manufacturers.
The single-filament 168 at 4.9W draws considerably less power than either filament of the 2357NA, reflecting a functional difference between the two generations of the parking light circuit in this model.
