Bob - Harbour Lights does(or did at one time) have a window/bumper decal. It is round and dark blue(like the blue color of the society boxes) and has the Harbour Lights decal in white. I've had one on my vehicles for the last 4 years. I think they were $2.00 a piece and I ordered right from Harbour Lights. They go on either the outside of your window or on your bumper.
