Additional Notes

The DE3423 and DE3175 are both festoon-type bulbs, meaning they are cylindrical in form and make electrical contact through metal caps at each end rather than through a base plug or pin configuration.
Both bulb types operate at 12 volts and conform to ANSI standards recognized in the United States and Canada.
The DE3423 has a length of 41mm, while the DE3175 has a length of 31mm. These two bulbs are not interchangeable due to this difference in physical size.
The Hyundai Sonata uses the DE3423 for the 2021-2023 luggage compartment, and the DE3175 for the 2018 luggage compartment.
Because the socket in a festoon application is sized to hold a specific bulb length, installing a 31mm bulb in a housing designed for a 41mm bulb, or vice versa, would result in a poor or failed connection at the end caps.
