LEDs or Light Emitting Diodes are a basic staple when you require visual feedback in your circuit design. They can be used to indicate power status, circuit failure, and even a frequency range when cascaded. We offer a large variety of different LEDs from 3mm to big 7.5mm sizes in an assortment of colors that include red, yellow, green, blue, orange, and infrared. We have Bi-Color, Tri-color and RGB flashing LEDs.
