- Oct 14, 2017 -

With the gradual decline of continuous improvement of LED technology and cost, after the LED lamp in the automotive electronics technology after verification, in recent years the concept car show preliminary design stage, more and more close to the prospect of a wide range of applications in the production car in the system. From the Audi R8 electronic system full use of LED lamps to start, BMW, Cadillac, Mercedes, TOYOTA and other companies have also launched their LED lamps to replace the traditional incandescent light bulbs, HID car models, new car considerably all kinds of LED lamps to attract the majority of a riot of colours, the attention of consumers, at the same time, also provides a a new bright spot for the automobile in the future, I believe there will be more car manufacturers will LED lamps as automotive lighting, indication, backlight and decoration of choice soon.

LED lights in the use of cars, mainly concentrated in headlamps, taillights, lights, car GPS backlight and other use, especially the LED taillights, accounting for about 45% of the entire market.
