Rear ended - brake/running lights malfunction

[Beem530i]

Hi all - I was struck from the rear at a roundabout the other day. I kept the bike upright and car that hit me did not stop. Looked okay initially but then noticed crack in taillight assembly. The turn signals still work but the brake and running taillight do not. Do I need to replace the entire taillight assembly or can i just replace the clear plastic cover and some bulbs? Thanks

Looks like the tail light is one piece https://shop.maxbmw.com/fiche/DiagramsM ... in=ZX71206
