The headlights we see every day usually integrate wide lights, high beam, low beam and turn signals, and the front fog lights of some vehicles are also included in the headlights.

Currently, the common forms of headlights on the market are mainly halogen, HID xenon and LED lights.

A halogen lamp is a tungsten lamp filled with halogen elements like bromine iodine or halide, also called tungsten halogen lamp, and it is a special kind of incandescent lamp. Halogen lamp is brighter and more durable than the traditional incandescent lamp, the light is white and yellow, with relatively low cost, and is now widely used in low-end vehicles. During production, lenses and reflective lighting principles are used in the construction of the lamp assembly to improve the efficiency of the light.

HID xenon headlights are high-pressure gas discharge lamps filled with a mixture of inert gases, including xenon gas. Unlike halogen lamps, xenon lamps do not have a filament, there is only one gas light-emitting point in the lamp, and the light is green-blue, which is brighter and less energy-consuming than halogen lamps, with a longer life span and a medium cost, seen mostly in mid-range vehicles.

LED headlights use LED as the light source. LED has high brightness, color variety, low power consumption, and long life. In recent years, due to the need for design, aerodynamic requirements and aesthetic needs of the car shape, low side streamline shape is becoming more and more popular, and the shape of the headlights is also developing towards exotics and integration. The cost is higher and is now mostly seen in high-end vehicles.
