Additional Notes

The DE3175 is a festoon-type bulb measuring 31mm in length with end-cap contacts, operating at 12V. It meets ANSI standards for the US and Canadian markets and is the specified dome light bulb for the Kia Niro across the 2023-2024 model years.
The DE3425 is a festoon-type bulb measuring 41mm in length with end-cap contacts, also rated at 12V and ANSI-compliant. It is specified for the rear dome light position across the 2021-2023 model years.
The 6461 bulb is a festoon type with an SV8.5 base, measuring 36mm in length and rated at 12V, 5W. It differs from the DE3175 and DE3425 in both base type and physical length, which affects interchangeability.
All three bulb types in these specifications are festoon-format bulbs, meaning they mount between two contact points at either end of the bulb body rather than using a screw or bayonet base.
The DE3175 and DE3425 share the same end-cap contact style but differ in length, at 31mm and 41mm respectively. This length difference makes them non-interchangeable despite their similar contact design.
The 2018 Kia Niro dome light uses the 6461 bulb, which carries an SV8.5 base. This base type is physically distinct from the end-cap contacts found on the DE3175 and DE3425, making cross-substitution between these types incompatible.
