Second generation (SX2, 2023-present) · Small crossover / B-segment SUV
Interior LED upgrades in the Hyundai Kona are one of the quicker cabin jobs. Nearly every fitting uses a small wedge (194 or T10) or a festoon bulb between 31 and 42 mm long; the code is printed on the metal cap of the existing bulb, and every kit worth buying lists its bulb code the same way.
Fourth generation (NX4, 2020-present) · Family crossover / C-segment SUV
Interior LED bulbs in the Hyundai Tucson are a size-code exercise first and a CANbus exercise second. Get the bulb code right (194, T10, festoon 31 or 36 or 42 mm, W5W or C5W), then decide whether CANbus-decoded bulbs are worth the small extra outlay given that this car is mildly CANbus-sensitive.
First generation (NE, 2021-present) · Family crossover / retro-styled D-segment electric hatch
Hyundai's CANbus is only mildly sensitive, so the IONIQ 5 does not usually need special CANbus-ready bulbs. Read the bulb code before you order, and replace the interior set together, because LEDs are commonly 6000K bright white and look obviously wrong next to stock incandescent bulbs.
Three products we would look at first in this category. Fit for your Hyundai still comes first: check the compatibility list on the listing against your exact model and year, and read the model guide above.
