Additional Notes

The DE3175 is the most frequently specified dome light bulb across the Kia Rio's listed model years, appearing in the 2001-2002 and 2006-2011 model years. It is a festoon-type bulb with a 31mm length and end-cap contacts, operating at 12 volts.
The 6461 bulb is a festoon type with an SV8.5 base and a 36mm length, rated at 12V and 5W. It is specified for the 2019-2020 Kia Rio dome light.
The 904 bulb is a miniature wedge type with a T10 form factor, rated at 12V and 8W. It is specified for the 2023 Kia Rio dome light.
All three bulb types listed carry the ANSI standard designation for the US and Canadian markets.
The DE3175 and 6461 are both festoon bulbs, but they are not interchangeable. The DE3175 uses end-cap contacts and measures 31mm in length, while the 6461 uses an SV8.5 base and measures 36mm in length.
The 904 wedge bulb and the two festoon types are physically incompatible with one another, as wedge and festoon bulbs use entirely different socket and retention designs.
The wattage of the dome light bulb changed across the listed model years. The 6461 is rated at 5W, the 904 at 8W, and the DE3175 carries no wattage specification in the provided data.
