The light systems are designed to fit around, or on, just about anything – SUPs, kayaks, canoes, trees, campers, ATVs, car hoods, popup tents, and many more. The patented harness setup will extend or shrink to meet your needs. Each system also comes with a set of extension straps to add length onto the harness, if needed. The hole in each end cap also offers space for zip ties, paracord, velcro, thumbscrews, or other fastening components. If you have a special application that you have a question about or need help with, please email email@example.com with some details. We’ll be happy to help light it up!
