All lights work on all 4 wings. Just needs a good amount of charging. 4 usb charger cords. Carried like 2 times and has just sat in my closet. the one wing was charged some but turned to a almost lights out blue. I believe that is just due to not being charged long enough. inside is fairly clean but never hurts to clean. I will not go any less, I have already came way down from what I originally wanted
