As LED (Light Emitting Diode) has the advantages of small size, high brightness, long life, low energy consumption, it has been widely used in automotive automotive industry. Specifically, the automotive lamp includes an instrument panel inside the car, an audio indicator, a backlight of the switch, a reading lamp, an external brake light, a taillight, a sidelight, and a headlight.

Incandescent lamps used in automobiles are not resistant to shock, are easily damaged, and have a short life span. They need to be replaced frequently. In 1987, China began to install high-level brake lights on cars. Because of LED's fast response, it can remind the driver to brake early and reduce the rear-end collision accident. In developed countries, the use of LED central rear high brake light has become the standard part of the car. The HP automobile tail light module introduced by HP in 1996. Groups can be freely combined into various car taillights. In addition, ultra-high-brightness light sources can be used as light sources in automobile dashboards and various other lighting sections, so LED displays are gradually adopted. China's auto industry is in a period of great development and is an excellent opportunity to promote ultra-high brightness LEDs. In recent years, an annual output value of RMB 1 billion will be formed. Within five years, an annual output value of RMB 3 billion will be formed.
