- Lamp housing
The lamp housing is the outermost part of the headlight, usually made of durable plastic or metal, which is used to protect the internal electrical components from the external environment. - Reflector (reflector bowl)
The reflector is an important component inside the headlight, usually made of aluminum or other metals. Its function is to reflect the light emitted by the bulb and control the direction and distribution of the light to improve the lighting effect. - Bulb
The bulb is the light source part of the headlight, usually including a filament and electrical connections. The light emitted by the bulb is reflected by the reflector to form a lighting beam. Depending on the model and needs, the bulb can be a halogen bulb, a xenon bulb or an LED bulb. - Light distribution mirror (lens)
The light distribution mirror is the transparent part inside the headlight, which is used to distribute and diffuse the light to produce a uniform lighting effect. The lens can also adjust the shape and distribution of the light as needed. For example, in a dual-light lens structure, the lens can achieve the switching of high and low beams. - Lighting adjustment device
The lighting adjustment device is used to adjust the angle of the headlight to maximize its lighting potential. Many vehicles are equipped with electric adjustment functions, and the driver can easily adjust the height of the headlight with a lever or knob. - Circuit boards and connectors
These components are used to connect the headlights to the vehicle’s electrical system and provide power to the bulbs to ensure that the headlights work properly. - Other components
The headlight assembly may also include auxiliary lighting components such as fog lights and turn signals. These components and the main headlights together form a complete driving lighting system.
