At night when running, walking, riding, danger is all around. On the car, on the arm, on the back, can be placed anywhere to let other pedestrians, vehicles to notice you, at any time to ensure your safety. Trapped in the mountains, waiting for rescue, with flashing to allow rescue teams to quickly find your location. Flashing off lights, screens can be used to protect your safety, but also can be used to send signals. Translated with www.DeepL.com/Translator (free version)
