Just to let everyone know, I received the illuminated door sills and tried an experiment. I tried getting them to light up green by placing a piece of yellow cellophane over the EL strip. It didn't quite work. Even with a few layers, the best I could get was a bluish green that did not have enough brightness. The sills were not difficult to take apart. The metal strip is secured to the sill using double sided tape around the whole plate. The EL strip is secured using the same sticky stuff that hold removable inserts in magazines. If anyone wants to experiment, go for it and let us know how it comes out.
