Velleman K8403: RGB LED Illumination for K8400 Vertex Kit (Electronic Project Kit - Soldering Required)

The Velleman K8403 LED Add On Kit makes it easy for you to add LED strips to your Vertex K8400 3D printer. You control the LED colors through a G-code command (M420) or from the K8400’s LCD controller. You can add the M420 command to your G-code to change color when a change occurs, for example when switching print heads (if you use the K8402) or for the ending of a print. This DIY kit contains everything you need for an easy install.
