This night light intuitively lights up in the color you choose. The night light has 3 modes. In mode 1, the night light recognizes the color of the surface it is standing on and lights up in the same. In mode 2, it shines in warm white light (2 light intensities) and in mode 3, it changes colors automatically. You can charge the night light with a micro USB cable. With one charge it can shine for about 24 hours. Thanks to the LED lights, the night light will not get warm. You can set the night light with automatic off mode or in continuous mode.
