Additional Notes

The 904 bulb is the most frequently specified map light bulb across the Kia Rio lineup covered in these specifications. It is an ANSI-standard miniature wedge bulb of the T10 form factor, rated at 12V and 8W.
The 168 bulb shares the same T10 wedge form factor as the 904 but draws only 4.9W compared to the 904's 8W. Both operate at 12V and conform to ANSI standards for the US and Canadian markets.
The DE3175 is a festoon-type bulb with a 31mm length and end-cap contacts, which is a physically distinct construction from the T10 wedge type. It is not interchangeable with either the 904 or the 168 without a socket adapter or housing modification.
For the 2006-2010 Kia Rio, the correct map light bulb depends on whether the vehicle is equipped with a sunroof. Vehicles with a sunroof take the 904, while those without a sunroof take the DE3175.
The sunroof-dependent fitment split does not apply to the 2011 and 2019-2023 model years, where the 904 is specified regardless of sunroof configuration.
The 2001-2002 model years use the 168 bulb, which, despite sharing the T10 wedge base with the 904, carries a lower wattage rating and is not listed as a substitute for the 904 in any other year within these specifications.
