Additional Notes

The DE3175 is the specified dome light bulb for the Hyundai Ioniq 5 across the 2023-2024 model years.
The DE3175 follows the ANSI standard, making it the recognized specification for the United States and Canadian markets.
As a festoon-type bulb, the DE3175 makes electrical contact through metal caps at each end rather than through a base socket, which is a defining characteristic of this bulb family.
The DE3175 has a 31mm length, a figure that reflects the physical span between its two end-cap contacts and is critical to proper fitment within the dome light housing.
The bulb operates at 12 volts, consistent with standard automotive electrical systems.
