How to Splice Rope Lights

A set of clear rope lights.

Rope lights are an easy, creative way to decoratively light your home. They are unobtrusive and easy to mount in a variety of areas, including along steps, under kitchen cabinets, lining walkways and even around your patio or deck. If you want to have different colored lights in one stretch of lights, you will have to splice rope lights together. Splicing is also an option when a section of the rope light stops working and you want to replace them. Made of miniature lights encased in flexible, translucent PVC tubing, it is easy to learn how to splice rope lights together to create a longer or more colorful run of rope lights.

Difficulty:

Moderate

Instructions

Things You'll Need

• Rope lights
• Sharp utility scissors
• Invisible rope light splicing kit (includes connectors and clear plastic tubing)
• Hair dryer

Instructions

1. Choose a strand of rope lights to splice that is compatible to your existing set. If your rope lights are 12 V, you must choose another 12 V rope light set. The same principle applies if you have a 110 or 120 V set. In addition, if your rope lights have two wire strands, you must choose another compatible rope light set to splice with two wires.

2. Look for silver line markers on the rope light that indicates where you can cut it safely for splicing. Typically, these silvery lines occur every 18 to 36 inches, depending on the length of the rope light.

3. Cut your existing rope light at the silver line marker of your choice using sharp utility scissors. Repeat the process with the second set of rope lights you want to join to your current set.

4. Slide a clear piece of plastic tubing from the invisible rope light splicing kit over one cut end of the rope light.

5. Clear plastic tubing and a splice connector.

   Insert the splice connector onto both ends of the cut rope lights. The splice connector is a round plastic disk with metal prongs sticking out both sides. The metal prongs will slide onto the wires inside the cut ends of each rope light you want to connect together. Push both ends of the rope light snugly onto the splice connector.

6. Slide the clear piece of plastic tubing over the new connection where the cut rope lights are now joined together and heat it with a hair dryer. The heat will shrink the plastic over the new connection to seal and protect it.

7. Repeat steps three to six for any remaining splicing connections.

Tips & Warnings

• Use a box knife or a PVC pipe cutter to cleanly cut through your rope lights. Make sure one of the rope lights you are splicing has a power cord and plug on the end.

• Unplug your rope lights before you cut and splice them to avoid electric shock. Do not cut the rope lights at any place other than the designated silver mark lines, or you may permanently damage the rope lights.
