LED in the automotive market is the main driving force for the growth of the replacement of the original indicator light bulbs, a car if all of the lighting into LED, the internal / external need to use about 200 ~ 300 LED. According to the current level of LED, a car is expected to require at least more than and 300 LED. It is generally believed that 3 to 5 years of automotive LED will become the main market for LED, will form an annual output value of about $1 billion, the market will grow rapidly with the breakthrough of LED technology.
