I draw in 3D this traffic light to train an AI model for traffic light recognition (I also have 3D models of traffic signs). Inside the box under the traffic light you can fit an ESP32 with an Li-ion Battery 18650 and its step up circuit that stabilise the tension around 5V. It also manage the charge of the battery. Inside the traffic light LED box you can add around 8 to 10 WS2812 RGB LED.
