New I30cw – very satisfied but a question

I have been driving a brand new i30cw with the big diesel and in full equipment for two weeks now. If there is simply a good track, processing and material quality have improved again significantly. Compared to its predecessor of 2010, almost everything has improved. Hyundai has done a lot of work! If there is now an automatic spacer for cruise control, it would be the perfect car in its class. Stop, one thing still bothers me: the lack of brightness of the Reversing lights and interior lighting. Is there a replacement with LEDs and if so, where?
