This may be a stupid question but I recently purchased a set of reconditioned headlights and upon arrival I noticed a part had broken off during the shipping process. I returned it and they sent me a replacement. The same thing occurred with the replacement as well. The company will no longer send me another replacement for reasons unknown. So my question is can I still safely install the headlight assembly with this broken piece? I've included pictures for referencing. Thank you for your response in advance.

 

Pictures are too zoomed in to see exactly what that piece is
