Kia Niro dome light bulbs use 2 distinct sizes: DE3175 and 6461 for the front dome light, while the rear dome light requires a DE3425 bulb size. The replacement chart covers vehicle production years spanning 2017 to 2024 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kia Niro dome light uses two distinct bulb types across its model years: the DE3175 for 2023-2024 and the 6461 for 2017-2019.
All three bulb types found in these specifications, the DE3175, 6461, and DE3425, are festoon-style bulbs, meaning they are cylindrical lamps that make contact at both ends rather than through a screw or bayonet base.
All bulbs listed operate at 12 volts, which is standard for automotive interior lighting systems.
The DE3175 is 31mm in length and uses end-cap contacts, conforming to the ANSI standard for the US and Canadian markets.
The 6461 bulb is 36mm in length and uses an SV8.5 base, which is a specific festoon base designation indicating a 8.5mm cap width. It is rated at 5W and also meets ANSI standards.
The DE3425 is the longest of the three festoon types at 41mm, uses end-cap contacts, and is the specified bulb for the Kia Niro rear dome light across the 2021-2024 model years.
Although the DE3175 and 6461 are both festoon bulbs operating at 12V, their differing lengths (31mm versus 36mm) and base types make them non-interchangeable.
The DE3425, at 41mm, is physically longer than both the DE3175 and the 6461, and substituting either of those bulbs in a DE3425 fitment would result in an improper fit.
The front dome light of the Kia Niro shifted from the 6461 to the DE3175 between the 2019 and 2023 model years, representing a change in both bulb length and base type.
