  LED car lights directly related to the development of LED light source associated. Semiconductor electroluminescence as early as 1907 found that the light is very weak, mass production difficulties and slow progress. 1968 the United States Monsanto launched light intensity of more than 20mcd GaAsp / GaAs structure of the red LED, as a breakthrough point, greatly accelerating the development of LED. And then have developed a light intensity of 1000mcd red, yellow, green LED, in the instrument, the signal of the signal received a preliminary application, the formation of the LED early application of the market often because of its light intensity, light attenuation and other performance indicators The problem can not be widely used in automotive lighting. Until 1990, the United States HP company, Japan's Toshiba introduced the light intensity of more than 1000mcd InGaAlP / GaAs structure of the red, yellow high-brightness LED and Japan's Japan in Japan invented InGaN / Al2O3 blue, green high-brightness LED as a symbol, from the technical And mass production for the automotive light source LED paved the way. 13 Led Light Bar   1985 LED car lights first appeared in the bus, in 1986 Nissan300zx car on the use of LED high brake lights marked the beginning of the era of LED car lighting. Internationally famous car brands such as BMW, Cadillac, Buick, Volkswagen, Ford, Mercedes-Benz, Toyota, Mitsubishi, Mazda and Skoda have launched LED car lighting. Led Fog Light For Cars   LED car lights to double the number of annual growth in 2005, the output value has reached 546 million US dollars, accounting for 14% of the world's LED applications. China in 2000 in Shanghai Volkswagen Santana 2000 first on the use of LED high brake lights. China's LED car lighting every year to 70% -80% of the rate of growth in 2006, the output value of more than 100 million yuan. The Brightest Cordless LED Worklight Tools Of The Trade
