How to connect a Light Emitting Diode properly: If you are going to use a power supply like a transformer, you should use an appropriate to reduce the voltage at or below the maximum allowed level. Do not apply excess current since the brightness will only increase by a just a little bit but the LED may fail sooner. Don't forget to check the direction of the light emitting diodes before soldering them.
