One of the transparent headlight covers on my Alternators Mirage seems to have come loose. Mirage has two sets of lights: an upper set and a lower set, each designed with a grey headlight piece covered by a transparent plastic piece. On mine, the upper left transparent plastic piece is loose. The transparent plastic piece has two tabs: a front tab used to position the piece correctly, and a rear tab that actually tabs in to the mounting piece. I've tried pushing the rear tab in place, but can't get it to go in properly. Is there some trick to getting this transparent plastic piece to tab in properly? I've pressed quite hard on the piece and it refuses to tab in. Has anyone else had this problem with Mirage or Rodimus?
