You need one tiny indicator that tells the operator red, green, or orange without three separate components. This 3mm tricolour LED does it. Drive red and green together and you get orange — no extra part, no extra wiring. The diffused lens keeps the glow soft so it reads clearly at a glance, not a glare in someone's eye. Common cathode means one shared ground pin. Drop it into a panel, a control box, or a prototype breadboard. 2.0V forward voltage, 20mA typical current. If your board is tight on space and you need three states from one footprint, this is the part
