10 Steps How to Fix Cut LED Lights

1. Gather the Necessary Tools

Before you begin to fix your cut LED lights, it is important to gather all of the necessary tools and materials. You will need a pair of scissors, electrical tape, a soldering iron, solder, and heat shrink tubing. Additionally, you may want to have a pair of needle nose pliers on hand for any additional work that needs to be done.

2. Cut off the Damaged Section

Once you have gathered all of the necessary tools and materials, you can begin to repair your cut LED lights. The first step is to cut off the damaged section of wire with the scissors. Make sure that you leave enough wire on either side so that you can splice it back together later.

3. Strip Both Ends of the Wire

Once the damaged section has been removed, use the scissors or needle nose pliers to strip both ends of the wire so that they are exposed. This will allow you to make a connection between them when you splice them back together later on in the process.

4. Connect Both Wires Together

Now it’s time to connect both wires back together again using either an electrical tape or solder method. To do this, twist both ends of wire together and then wrap them with electrical tape or solder them together depending on what method you decide to use. Make sure that there are no gaps in between where air could get through as this could cause an electrical short circuit and damage your LED lights further.

5. Cover Connection with Heat Shrink Tubing

After connecting both wires together again, it is important to cover the connection with heat shrink tubing in order to protect it from any moisture or debris that could cause an electrical short circuit or corrosion over time.

To do this simply slide one end of heat shrink tubing over each end of the wire before connecting them together and then slide it down over the connection once they have been joined together securely. Use a heat gun or lighter flame to shrink down the tubing until it fits snugly around the connection point before moving on to the next step in repairing your LED lights.

6. Test Connection for Continuity

Now that your LED lights have been re-connected again using either an electrical tape or solder method it is important to test for continuity before powering up your LED light string again. To do this use a multi-meter set on ohms mode and touch one lead from each end of the wire connection point. If there is continuity then your LED lights should power up without any issues, however, if there isn’t then go back and check all connection points before trying again.

Use a Multi Meter Set on Ohms Mode

7. Insulate Connection Points With Electrical Tape

Once testing has been completed successfully, go ahead and insulate all connection points with electrical tape. This will help protect against any potential shorts occurring while also helping keep out dirt and debris that could interfere with performance.

Additionally, using electrical tape on exposed wires is a great way to reduce the potential for short circuit fires or shocks. It’s also possible to find specialized LED connection tape that will help ensure proper connections between wires and LEDs. This type of tape offers additional protection against weather and other environmental conditions that could damage wiring and lead to failure.

8. Reattach Lights To Power Source

With all connections now secure, reattach your LED lights back onto their power source ensuring everything is connected correctly as per manufacturer instructions. Once complete, turn on the power source and test the LEDs for proper operation. If you notice anything out of the ordinary with your LEDs, such as flickering or dimming, you may need to adjust the voltage accordingly.

9. Check All Connections For Security

It is always important after completing any repairs like these, especially when dealing with electricity, to double-check all connections for security before leaving them unattended. Look for signs such as loose wires, frayed insulation etc which could potentially cause problems down the line. If it is at all possible, use shrink-wrap to make sure the connections stay secure.

10. Clean Up Work Area and dispose Of Any Waste Responsibly

Finally, once repairs are complete ensure the work area is cleaned up properly by disposing of any waste responsibly such as used electrical tape etc. in accordance with local regulations. Be sure to turn off all electrical power sources that were used in the repair process, such as lights and other power cables. It is also advisable to test the repaired LED light after installation to ensure it is working correctly before putting it back into use.

Turn Off All Electrical Power Sources
