Disconnect the device from its power source.
Remove the cover of the device that contains the LED. Most LEDs are on the surface of devices and have covers or panels that can be removed to access the LED.
Find the connection point of the LED and its circuit board. LEDs have two wires extending from their base that are called a cathode and an anode.
Cut the cathode and anode with wire cutters at the base of the circuit board. Make sure to cut them close to the board as longer wires can touch and create a short circuit that can damage the device's circuitry.
Remove the cut LED light from the device. If left in the device, the cut LED can interfere with the function of the device and its circuitry.
Replace the cover or panel that was removed to access the LED light.
