Additional Notes

The Kia Rio5 map light specifications cover the 2006-2011 model years, with two distinct bulb types appearing across that range depending on vehicle configuration.
The 904 is a T10 miniature wedge bulb rated at 12V and 8W, conforming to ANSI standards for the US and Canadian markets.
The DE3175 is a festoon-style bulb with a 31mm length and end-cap contacts, also rated at 12V and conforming to ANSI standards for the US and Canadian markets. Unlike the 904, no wattage figure is listed for this type in the specifications.
The two bulb types use fundamentally different mounting systems. The 904 uses a wedge base, while the DE3175 uses end-cap contacts at each end of the festoon body, making the two types physically non-interchangeable.
For the 2007-2011 model years, the Kia Rio5 requires the 904 bulb when equipped with a sunroof, and the DE3175 when the sunroof is absent, indicating that the sunroof option is tied to a different map light housing design.
The 2006 Rio5 is listed with only the DE3175, with no sunroof-related variant noted for that year.
A production date cutoff is noted for the 2010 model year. The DE3175 fitment applies only to vehicles without a sunroof built up to 3/22/2010, making the build date a relevant factor when selecting the correct bulb for that year.
