Purchased on 12/7/2023 from a well-known car accessories chain in Attica A******S. Two boxes of 2 pieces each worth €180. Beautiful lamps, amazing color, perhaps the strongest I've tried and seen in a car. In December 2024, one of them turned purple from white. I asked this specific store to replace them with new ones since I had been informed then that there is a one-year warranty, but suddenly the warranty never applied. No willingness to assist a customer who spent so much money. Be very careful with this particular store and where you put lamps; within the European Union, things have a minimum one-year warranty. After 3 days of going back there, the second lamp had also turned purple. Maybe I was the exception, maybe not!
