You can cut the strip to be any length you need, but you must cut along the dotted lines. The cutting distance, or the distance between the dotted cut lines, can vary depending on the manufacturer. If you don’t cut along the indicated lines, some of the lights will not turn on.
Lightly tug at the strip to make sure it’s securely locked into the connector. You can find connectors at hardware stores, electronic stores, and online.
Give the wires a gentle pull to make sure they’re firmly attached.
Cover the LED strip with a plastic or aluminum casing to keep them protected.
The wires connected to the LED lights need to be plugged into a power source correctly in order for the light to turn on. Generally, red wires indicate a positive connection and black wires indicate a negative connection. You may not be able to tell which wires are positive or negative due to their coloring or lack of labeling. [5] X Research source
Be sure to use a functioning wire that you want to tap power from for your LED lights. Use a splicer with a gauge that fits over the wire you want to tap. You can find splicers at hardware stores and online.
Usually, the positive wire will go into the slot on the right and the negative wire on the left. You don’t have to strip the sheathing around the wires
Don’t snap down the pliers or squeeze too hard or you could crack the splicer.
The cover will keep the pin of the splicer from coming into contact with anything and prevent power from escaping the wire.
The LED lights will turn on whenever the tapped wire has power running through it.
