Additional Notes

All luggage compartment bulb sizes listed for the Hyundai Tucson across 2005-2023 are festoon-type bulbs, a form factor characterized by a cylindrical glass tube with contacts at each end that seat into spring-clip holders within the fixture.
The DE3425 and DE3423 are both 41mm festoon bulbs operating at 12V with end-cap contacts, making them physically identical in length despite carrying different part designations.
The DE3175 is a 31mm festoon bulb with end-cap contacts rated at 12V, and its shorter body makes it incompatible with fixtures designed for 41mm bulbs even though the contact style is the same.
The 6461 is a 36mm festoon bulb with an SV8.5 base rated at 12V and 5W, and its base type differs from the end-cap contact style used on the DE-series bulbs, making cross-substitution between these groups unsuitable.
All four bulb types conform to ANSI standards applicable to the US and Canadian markets.
The Hyundai Tucson (2021-2023) uses the DE3425, while the 2016-2020 model years use the DE3175, meaning these two groups require different bulb lengths despite sharing the same end-cap contact style.
The 2014-2015 model years use the DE3423, which shares its 41mm length and end-cap contact style with the DE3425 used in 2021-2023, though they carry distinct ANSI designations.
Model years 2005-2013 use the 6461 bulb, whose SV8.5 base represents a structurally different mounting interface compared to the end-cap festoon bulbs specified for all subsequent model years.
