Transparent 5mm LED (Pack of 10) Color:Yellow Reduction Ratio: 1:64LEDs make great indicator lights. They use very little electricity and they pretty much last forever. You cannot directly connect an LED to a battery or voltage source. Firstly, because the LED has a positive and a negative lead and will not light if they are the wrong way around and secondly, an LED must be used with a resistor to limit or 'choke' the amount of current flowing through the LED otherwise the LED could burn out! LEDs are ideal
