3 LED light bars that connect on to the axis of a Flux 3dp. The light bars are made for 8mm LED tape. I am using a 12v system with a 12v power supply. I have also included the pictures of the packaging for the switch and the power connector the bars are designed to fit. The bars snap onto the axis rods and don't interfere with the belts or trucks. just keep them low enough out of the travel area.
