AHHHHH!!!!!!! Just read this thread and found out they're supposed to go on the outside!!! I took off my bumper- took out the headlamps- and then took them apart and put the overlays over the corners themselves.
It was hard to get them to look good and I was starting to wonder how others were able to get them to look ok. Ohh man- this has taken me 4 hours to do and lots of broken parts- and now I'm unsure if I even want to keep them like this.
Just for refference Blue Batmobile- maybe add an insert telling those who buy these overlays- that they're supposed to go on the outside. I may now look for possible clear corner inserts or just order another set from you. (sad1)
P.S. The overlays in my sig are digital ones lol.
