This is a custom automated traffic light display cabinet that I built for the lobby at the place I used to work at. It has a built in computer monitor that can hook up to a laptop to stream content. The traffic light is controlled by a custom motion sensor. When motion is sensed, the signal turns green for 4 minutes and then yellow and red. It rests on red until motion is sensed again. There is also an included usb charger in front under the monitor for guests to charge their phones. LED lighting illuminates both shelves. You will need several people to carry this as it's extremely heavy! I accept cashapp, paypal, or physical cash.
