Terminating a C7 or C9 light string
We get calls, quite often actually, about how to end a light string without a plug. There are a few main ways to seal off the end of a light string, Electrical Tape, Liquid Electrical Tape/Insulation, or Heat shrink.
Electrical tape is the most convenient and fastest but sometimes in the weather it can shrink and unravel if not applied properly.
Heat Shrink is a personal favorite of mine. It's safe, long lasting, and looks great. Be sure to use the proper size, in my experience the small the better.
I hope this gives some insight as to how we make custom light strings and how to properly terminate a C7 or C9 Stringer.

Electrical tape is the most convenient and fastest but sometimes in the weather it can shrink and unravel if not applied properly.
- Always Cut Electrical Tape - Use scissors or a knife to cut your tape, pulling/tearing the tape stretches it and will lead to it shrinking in the weather
- Separate both wires and wrap individually, then together. You don't want to risk a short across the exposed wires.
- Wrap tightly, but again, do not stretch the electrical tape.
Heat Shrink is a personal favorite of mine. It's safe, long lasting, and looks great. Be sure to use the proper size, in my experience the small the better.
- Separate the wires and heat shrink individually. Leave excess on the end so that the end of the wires do not touch. I leave enough to fold over after first shrink process
- Hit it with a heat gun for a few seconds
- Fold the ends of the excess heat shrink down after you shrink it onto the wires
- Slip a larger piece of heat shrink over both wires, making sure you keep the folded heat shrink down
- Hit it with heat gun and you should have a nice looking, well protected tip of your wire.
I hope this gives some insight as to how we make custom light strings and how to properly terminate a C7 or C9 Stringer.
