Rear light cracked (Facelift)

Hello guys, unfortunately I damaged the rear light cover yesterday at my Stinger (back right). The plastic is broken and a small gap (1x1mm) is visible. Maybe you know if the plastic alone (i.e. only the Celon) can be bought as a spare part? (I’m afraid it’s not :-). Maybe someone knows where to move isch there priceably…? Thank you very much!
