if you ask me it would look sop much better with the taillights higer up , like a tad under the upper bodyline and on the far corners ..
if you would dril holes in the corners and then put the drill in straight (like the tails would face back) you would have a hole where you can put in a small piece of tubing and mold that into the bodywork and on the tube that just sticks out you can put a nice bullet shaped lense , those are easy to make from red sprue in a drill with some sandpaper
if you want a explanation in dutch just pm me
