I bought several sets of these reflectors as extras for my Goldwing Trike. I've had issues with similar ones in the past as mentioned in some comments where they crash slightly shortly after installation. Since the supplied double-sided tape is the same size as the reflector, only the thin edge of the reflector comes into contact with the tape - the smaller the contact area, the easier it is of course to knock off. By cutting some of the tape (so it fits snugly into the reflector's flat recess) surface contact with the reflector is improved while leaving enough contact space to stick to whatever you need to attach it to. Simple photos are attached. - I had no problem keeping them in place with this little trick.
