These were a special order for a project and we had some extra made for us. 5m long XK glow strips, can be cut at certain cut points marked on the strip if needed (not just anywhere). You would need to get a normal XK Kit with the wiring and controller for it to work. In this project we did a whole B Trail on H permit lengths, we needed to fit an extra controller to avoid fade drop as we went so long. All controlled by the app on your phone, here we tested it out to music, not the best recording as taken on a phone but you get the idea. If you've seen the XK kit's we have and the videos and photos there, but have a bigger project in mind these are just what you need.
