Best Way To Make Custom Extension Cords for Christmas Lights
Making your own cords saves time, money, and lets you build exactly what you need for each display. Here’s a quick step-by-step guide to build safe, durable cords using male and female vampire plugs.
What You’ll Need
- Zip cord (SPT-1 or SPT-2)
- Male and female vampire plugs
- Wire cutters
- GFCI outlet for safety
Step-by-Step Instructions
1. Cut the Cord Cleanly
- Use the end of your cutters, not the hole near the hinge — that won’t cut cleanly.
- Cut so you get a flat, even end without any copper strands sticking out.
- For extra safety, cut the cord at a slight angle so one wire is shorter — it helps prevent shorts if water gets in.
2. Install a Male Plug
- Slide the cord into the end of the plug (not the side).
- Push it down firmly so the metal teeth bite into the wire insulation.
- Snap or slide on the cap — the side with a small “ramp” should face the wire.
- If it’s cold, use the flat side of your cutters to push the cap tight (keep your hands clear).
3. Install a Female Plug
- Do the same process on the other end of the cord.
- Always end a line with a female so there are no exposed prongs.
- Make sure the cap is snug and sealed to keep moisture out.
4. Add Inline Females (Optional)
- Each female plug has a small knockout tab — grip and pull it out with your cutters.
- Line up the plug where you want it on the cord and push the wire down into the plug.
- Snap on the cap to secure it.
- You can add as many inline females as needed, but only one male per cord.
Perfect for bushes, rooflines, or runs where you need several outlets along one cord.
5. Test and Finish
- Give each plug a firm tug — it shouldn’t move.
- Make sure there’s no exposed copper.
- Plug it into a GFCI outlet to test before using it in your display.
Quick Rules to Remember
- One male per cord
- Always end with a female.
- Angle your cuts to reduce shorts.
- Keep connections off the ground.
- Use GFCI protection outdoors
