Function introduction: 1.Apply thermal energy storage, build-in radial and vibration sensor. Install them in the front, rear or side windows of the car. 2.When the car is driven at night, four LED lights will shoot strobe and extreme red-laser or blue-laser, which has strong penetrating power and also functions as the decoration and caution. 3.When the car stops at night, four LED lights will go to a stand-by situation automatically after a certain period of working in order to save electric energy. Product characteristics: 1.Have build-in radial sensor, which will sense the strength of the radial, so that it will be in energy storage situation and will not shine in the day time. 2.Have build-in vibration sensor. When the car is driven at night, four lights will shine alternately; and when the car stops, they will go to a stand-by situation automatically. 3. Set up power switch which can be manually adjusted freely. 4. Use solar ray to charge up, which is bottomless.
