LED have been widely used in the automotive industry due to their small size, high brightness, long life and low energy consumption. Specifically, the automobile lamp includes an instrument panel inside the automobile, an audio indicator lamp, a backlight of the switch, a reading lamp and an external brake lamp, a tail lamp, a side lamp, and a headlight.

Automotive incandescent lamps are not resistant to shock, damage, and short life, and need to be replaced frequently. In 1987, China began to install high-position brake lights on cars. Due to the fast response speed of LEDs, drivers can be reminded to brake early and reduce rear-end collision accidents. In developed countries, central rear high-position brake lights made of LEDs have become standard parts of automobiles. LED automotive taillights models introduced by HP in 1996. Groups can be combined into a variety of car taillights. In addition, in the car dashboard and other various lighting parts of the light source, can be used with ultra-high brightness light, so they are gradually adopting LED display. China's automobile industry is in a period of great development and is an excellent opportunity to promote ultra-high brightness LEDs. In the next few years, an annual output value of 1 billion yuan will be formed, and an annual output value of 3 billion yuan will be formed within 5 years.
