Connect the extension cable to each end of the joined strips, making sure that the positive and negative wires are connected properly. Again, use electrical tape or heat shrink to secure the connections if desired. It will also help to ensure a good connection.

6. Secure Connections:

Use Zip Ties or Adhesive Tape

Use zip ties or adhesive tape to secure the connection and ensure it stays intact. This will help ensure that your lights won’t be pulled apart by accidental tugging, so make sure you do this step well! If you plan to hang the lights, make sure to use zip ties around the connections to keep them in place.

7. Connect Extension Cable to Power Source:

Once everything is secured, connect the extension cable to a power source using LED strip connectors or solderless plugs (depending on what type of connector you chose). Double-check all connections before turning on the power switch. Always ensure that the connections are secure and in the proper direction (positive to positive, negative to negative).

8. Test the Lights:

Turn on the power switch and test to make sure that your LED lights are working properly, paying attention to any flickering or dimming. If there is a problem, immediately turn off the power switch and check your connections again. Additionally, make sure that the lights are not too hot to touch.

9. Install and Hang Lights:

Depending on where you’re installing your LED strip lights, you may need to use mounting hardware and clips. Make sure to read all manufacturer instructions carefully before proceeding with the installation. You can also check out YouTube tutorials for proper placement and hanging tips.
