Measure out and cut the rope light to the required length. The maximum run for 120V neon rope light is 150 feet; if you have a longer run, you will need additional power supplies. Only make cuts along the cut lines marked on the PVC insulation every 18 inches. Cutting outside of these lines will cause that section not to light. The rope light comes with four power pins, four end caps, eight 4-inch sections of shrink tube, and a power cord. If splicing two colors together, cut each at a cut line, then connect using one of the power pins. Slide the section of shrink tube over the connection and heat so that it seals the connection. The pins are not flexible, so only make connections where you don’t need a tight curve. Use an end cap to cover the end of the rope light not connected to the power supply and on the other end, secure the power adapter. Install the mounting clips or tracks, then gently push the rope light into the track until it clicks in place.
