LED brake lights, that is, the material used is LED. brake lights made of LED, no radiation, no pollution, long service life, the theory of 60,000 hours, that is to say, in the car during the end of life without having to change the bulb.
However, the price of LED brake lights is more expensive, so the popularization of its use has formed a certain impact. In developed countries, LED brake lights have been used in large quantities, and in China, the development in the past two years has begun to accelerate.
