Remodeling a deceptive light band, replace it?

Hello, I wanted to ask if someone has dealt with the “light band” between the rear lights, if there are possibly already approaches for an exchange for a real lighting?? My dealer said when ordering my vehicle in February/March that there should already be a replacement bar at Amazon. However, I have not found anything there yet. Maybe there is someone still looking for and knows more about it… would certainly be a nice gimmick for the accessory trade. If it would be permissible at all?!?
