Revain's fitting guide says they fit my 2017 Kia Niro. LED lights are NOT suitable. The physical bulb fits into the socket. However, there are 3 rows of LEDs (see image). Because of this design and the way LED bulbs are positioned for operation, the area of the LEDs is too wide to fit between the positive and negative terminals of the bulb socket. If these LED bulbs were just two rows of LEDs, they could fit. Hope that helps.
