Welcome to kjdElectronics!
A dozen RGB LEDs in diffused white casing. Three of the 4 pins controls Red, Green and Blue while the other one is Common Anode. Ideal for color displays, indicators, diagnostic or analytical equipment.
This is a 50 piece pack of red only LED 5mm bulbs. Great for your next project, board lighting needs, or just to have as a part kit for any future needs. These bulbs do not have built in resistors. If you would like less bulbs and more parts, check out the Adafruit Parts Pack, or the Arduino Starter Kit.
