Headlights refer to lamps on vehicle.

 

Headlight combination
Combination headlight is at the front of car, it mainly serves as a lighting and signal. Light emitted by headlight can illuminate road conditions in front of vehicle, allowing driver to drive safely at night.
Combination headlights can be divided into: halogen tungsten lamps and xenon lamps according to light source.
According to the function, they can be divided into:
(1) Low beam.
(2) High beam.
(3) Front turn signal.
(4) Front position lamp (also called width lamp, indicating position lamp of vehicle), front fog lamp. Fog lamps are not mandatory in national regulations, and are basically equipped on all models.

 

Rear lights (taillights)
Combination taillights are located at the rear of car. They mainly serve as lighting and signaling. Rear lights generally consist of:
(1) Brake lights.
(2) Rear fog lights.
(3) Rear position lights.
(4) Rear turn signals.
(5) Reversing lights.
(6) Retroreflectors.

 

Halogen headlights
Halogen lamps are actually a special type of incandescent lamps. Principle is that when current passes through a resistor, it will generate heat. When temperature is high enough, it will emit blackbody radiation with a wavelength in visible light band. There are generally two types of halogen lamps: iodine tungsten lamps and bromine tungsten lamps. Principles are same. Halogen lamps have been widely used in the field of automotive lighting.

 

Xenon lamps
HID is abbreviation of High intensity Discharge high pressure gas discharge lamps, which can be called heavy metal lamps or xenon lamps.

 

 

Fog lights
Mounted at the front of car slightly lower than headlights, they are used to illuminate road when driving in rainy and foggy weather. Because visibility is low in foggy weather, driver's vision is limited. Light can increase driving distance, especially strong light penetration of yellow fog lights, which can improve visibility of driver and surrounding traffic participants, allowing oncoming vehicles and pedestrians to see each other from a distance.
LED lights
Light Emitting Diode, referred to as LED, is called light-emitting diode in Chinese. LED light strips refer to LEDs assembled on a strip-shaped FPC (flexible circuit board) or PCB hard board, and are named because their product shape resembles a strip.
Daytime running lights
Daytime running lights should be automatically turned on after vehicle engine is started. After dark, driver needs to manually turn on conventional lighting lights, and daytime running lights will automatically go off. Daytime running lights make it easier for other "road users" to see car, and they consume less energy than current low-beam headlights.
LED daytime running lights installed on the front of car body are lamps that make vehicle easier to recognize when driving during day. Its function is not to enable driver to see road clearly, but to let others know that a car is coming. Therefore, this lamp is not a lighting lamp, but a signal lamp.

 

Brake lights
It is brake light. It is divided into two categories: left and right brake lights (two) and high-mounted brake lights (one).
Left and right brake lights are important components of rear lights, one on the left and one on the right, distributed in rear lights on both sides. It is red, and red means warning. Light will light up as soon as brake is pressed (including handbrake). Brake light is to remind vehicle behind to slow down or stop, so that car behind can prepare in advance. Today's brake lights can also be divided into fog lights, which can penetrate thick fog. There are also LED lights as brake lights.
High-mounted brake lights are generally installed on the upper part of rear of car, so that vehicle behind can easily find brakes of vehicle in front, so as to prevent rear-end collisions. Function of high-mounted brake light is to warn vehicle behind, thereby avoiding rear-end collisions.
Reversing lights
Reversing lights are automatically turned on when driver shifts into reverse gear. They are white and transparent, and are mainly used to alert vehicles behind (I am reversing).
Retroreflector
In the rear of car, it plays a reflective role. When car behind shines on it, no matter from which direction, it can return along original path and shine in the eyes of driver behind, playing a prompting role. (Here, law of physical light reflection at right angles to original path is followed).
Turn signal
A lamp used to indicate left or right turns to other road users. Regulations require it to be amber.

 

License plate light
License plate light is mainly used to illuminate license plate, so that people can identify vehicle license plate in the dark.

 

Front turn signal
In headlights of car, it flashes to inform others that your car is turning. Color is amber.
Side turn signal
On both sides of car, some are embedded in front of car's reflector, flashing to inform others that your car is turning. Color is amber.
Rear turn signal
In rear lights of car, it flashes to inform others that your car is turning. Color is amber.
High beam: illuminates road ahead of vehicle at a long distance
Low beam: illuminates road ahead of vehicle without causing glare or discomfort to oncoming vehicles and other road users
Turn signal: used to indicate to other road users that vehicle is about to turn right or left
Brake light: indicates to other road users behind vehicle that vehicle is braking
License plate light: used in the space of rear license plate of vehicle
Front position light: indicates presence and width of vehicle when viewed from the front of vehicle
Rear position light: indicates presence and width of vehicle when viewed from the rear of vehicle
Retro reflector: a device that uses reflected light from an external light source to indicate presence of vehicle to an observer near light source
Front fog light: a device used to improve road lighting in fog, snow, rain or dust
Rear fog light: a lamp that makes vehicle more visible when viewed from the rear of vehicle in heavy fog
Reversing light: a lamp that illuminates road behind vehicle and warns other road users that vehicle is or is about to reverse
Outline light: a lamp installed at outermost edge of vehicle or near the highest roof to indicate width of vehicle
Side marker light: a lamp that indicates presence of vehicle when viewed from the side of vehicle
