Additional Notes

The DE3175 is the dome light bulb size across all available model years of the Hyundai Kona Electric, spanning 2019-2024.
The DE3175 follows the ANSI standard, which is the recognized specification framework used in the United States and Canada for automotive lighting components.
As a festoon-type bulb, the DE3175 is cylindrical in form and makes electrical contact through metal caps at each end rather than through a base socket, which is a defining characteristic of the festoon format.
The DE3175 has a 31mm length, which is the figure that distinguishes it from other festoon bulbs such as the DE3021 (28mm) or the DE3022 (36mm), making length a critical factor in fitment.
The bulb operates at 12 volts, consistent with the standard low-voltage electrical systems found in automotive interior lighting applications.
Because festoon bulbs of similar length can carry different end-cap configurations or voltage ratings, substitutions should be verified against the DE3175 specification before use in the Kona Electric.
