The Hyundai Tucson side marker utilizes a 12961 bulb size for the lighting components located on the exterior of the vehicle. Data for the specified component covers a range from 2005 through 2024.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the dominant type across the Hyundai Tucson side marker specifications. It follows the ANSI standard used in the United States and Canada, operates at 12V with a 4.9W output, and uses a T10 miniature wedge base.
The PY21W bulb is an ECE-standard type used in European and worldwide markets. It is a single-filament amber bulb rated at 12V and 21W, and it uses a BAU15s bayonet base rather than a wedge fitting, making it physically and electrically incompatible with 168 sockets.
The Hyundai Tucson rear side marker uses the PY21W bulb for the 2021-2022 model years, while all earlier rear side marker entries in the specifications use the 168 bulb. These two bulb types are not interchangeable due to their different base designs and wattage ratings.
For the 2016-2018 front side marker and the 2016-2020 rear side marker positions, the 168 bulb fitment is conditional on the vehicle being equipped with halogen capsule headlamps, indicating that alternative lighting configurations exist for those model years.
The 2014-2015 rear side marker entries specify the 168 bulb only on vehicles without LED tail lights, reflecting a trim-level dependency where the lighting package affects bulb fitment.
The front side marker position uses the 168 bulb without any conditional qualifiers for the 2005-2015 model years, covering the full range of those entries uniformly.
