Additional Notes

The Hyundai Veloster luggage compartment uses two distinct festoon bulb sizes across the 2019-2021 model years: the DE3175 and the DE3425.
Both the DE3175 and DE3425 are ANSI-standardized bulbs recognized in the United States and Canada, operating at 12 volts with end-cap contacts on either end of the bulb body.
A festoon bulb is a cylindrical lamp that bridges two contact points at its ends rather than using a base socket, making physical length a critical fitment factor.
The DE3175 measures 31mm in length, while the DE3425 measures 41mm, a 10mm difference that makes the two bulbs physically incompatible with each other's housings.
The 2019-2020 Veloster luggage compartment takes the DE3175, whereas the 2021 model requires the longer DE3425, meaning the two generations of this application are not interchangeable.
Installing a DE3425 in a housing designed for the DE3175, or vice versa, risks poor contact, intermittent function, or failure to seat properly due to the length mismatch.
