I finally changed the dim headlights to LEDs on my 2018 Tucson. I tried to install different H7 LED headlight bulbs, but failed. Because the oem headlight bulb has the black retainer. It requires a adapter if you want to change oem halogen bulb to LEDs. I google "hyundai tucson headlight bulb adapter", and found a Youtube video about 2018 Tucson headlight bulb adapter. It's very easy to change oem halogen bulb to LEDs with the retainer adapter. Here I share my installation process:
1. The OEM headlight bulb retainer
2. The headlight housing socket
3.Install H7 led headlight bulbs(with the retainer adapter)
Much brighter than oem halogen headlights. Amazing!!!
