why didn't you just buy some Tester red paint and paint it?? In the "Installs" page on this site there's a page that show you how to do it and where to get the paint. i'm planning on doing that this summer.
because the headlight painting is MUCH more difficult...not everyone wants to uninstall their whole headlight assembly (both of them), bake them in an oven, paint them, put them back together, and re-install.
the painting does look nicer, but it's harder work. but thats why vinyl overlays exist in the first place--ease of install.
