My Alla LEDs are great. I don't hear any noise in my 2020 Niro EV mostly because i have the music playing. If any noise it is so minimal that my old ears don't hear them anyway. They are better than the factory LEDs on the plug-in hybrid. Why, because I took my car to the dealer and parked next to a Niro hybrid plug-in and compared the two. The salesman concluded mine were a little brighter and had a better cutoff. I changed the backups to LEDs and there is a world of difference too.Any long term updates on these LED kits. I'm leaning towards the Ultra 2. How are the Alla bulbs holding up? Is the fan noise audible? Any shadows in the beam?
