Hyundai Tucson Trunk Bulb Size

The Hyundai Tucson trunk utilizes DE3175 and DE3423 bulb sizes for illumination within the rear cargo area. Available data for the specified components covers a span from 2005 through 2022.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The Hyundai Tucson trunk bulb specifications cover two distinct festoon bulb types: the DE3175 and the DE3423. Both conform to ANSI standards applicable to the US and Canadian markets and operate at 12 volts.
Festoon bulbs are cylindrical lamps that make electrical contact through metal caps at each end rather than through a base pin or wedge. This end-cap contact design is shared by both the DE3175 and DE3423.
The DE3175 and DE3423 differ in physical length. The DE3175 measures 31mm, while the DE3423 measures 41mm. Because trunk lamp housings are sized to hold a specific bulb length, these two types are not interchangeable.
The Hyundai Tucson (2015-2022) uses the DE3175 bulb for the trunk. The 2021 and 2022 model years are not separated by any change in bulb specification, and neither is the 2015-2017 range.
The 2019 model year carries a production date qualifier: the DE3175 specification applies to vehicles produced from August 15, 2018 onward. Vehicles built before that date fall outside this specification entry.
The DE3423, the longer 41mm festoon bulb, is specified for the Tucson trunk across the 2005-2014 model years. The 2005 entry is limited to vehicles produced up to July 8, 2005.
The 2018 and 2020 model years do not appear in the provided specifications, so no trunk bulb size is attributed to those years within this data set.
Installing a DE3423 in a housing designed for the DE3175, or vice versa, risks poor contact or physical incompatibility due to the 10mm difference in bulb length.
