This video explains how to create traffic lights designed for a G-scale outdoor model railway. The models are designed in FreeCAD and then printed on a 3D printer. The traffic lights are designed for controlling cars, but could be adapted for a railroad crossing or as lights controlling the trains approaching points or single track.
These are created from scratch using basic tools in FreeCAD. The traffic lights are designed for 8mm LEDs which will be controlled using a Raspberry Pi Pico or an Arduino like circuit created using a custom PCB.
