Headlights are a mandatory part of all cars. Vehicles must have functioning headlights at all times, even during fog or darkness. There are many types and styles of headlights available on cars today.

What are they for? 

Headlights help drivers see while driving at night or in poor weather conditions. They also allow drivers to see around corners and in front of them. 

When you need to drive at night, having headlights on your car is a must. The best headlights for cars in China  help drivers see around them and make it easier for them to see where they're going. Not having headlights can be dangerous, particularly if you're driving in a dark area or on a busy highway.

Different types of headlights are available for cars. Some headlights are mounted on the front of the car, while others are placed on the back. Both types of headlights can be useful, but front-mounted headlights are more common because they give drivers a better view of the road ahead.

Front-mounted headlights work by directing light forward, which makes it easier for drivers to see in all directions. They also create an illuminated "box" that extends in front of the car. This box helps drivers see other vehicles and obstacles in their way as they drive.

Back-mounted headlights work differently than front-mounted headlights. Rather than directing light forward, back-mounted headlights reflect light back into the driver's eyes from above and behind the car. Because these lights reflect off objects in front of the car instead of shining directly down on them, back-mounted headlights provide less illumination than front-mounted headlight systems.
