As the saying goes: The eyes are the windows of the soul. The lights look like the eyes of the car and are the silent language of the driver. With the development of science and technology, more and more functions of the car lights, the safety function of the car lights is also increasingly important.

First of all, let's talk about the history of the lights. Before 1887, headlights were not the main configuration of the car. Until a driver got lost in the dark wilderness, he relied on the peasant's hand-held light guide to get home. People gradually realized the importance of the lights, so someone used reflectors and kerosene lamps to make the initial prototype of car lights. However, soon this method was quickly eliminated in the shortcomings of the kerosene lamp itself, and the acetylene lamp became a new choice. However, acetylene as a raw material must be shaken to ensure work, and harmful substances may be generated when it is burned. In 1898, when the incandescent era arrived, the tungsten filament replaced the original carbon filament and ensured the stability of the headlights. In 1995, the advent of LED made the development of the car lights enter a new stage.

Next, let's take a look at some of the little common sense about the lights. I do not know if you have any questions about the color of the lights. Why is the rear light red? Why does double flash look yellow?

Red is the farthest wave band in the spectrum, it has a strong penetration, and it indicates the warning effect. This is why the rear lights are red. The brightness of the lights is also worth our attention. The lights are not as bright as possible. Everyone thinks that the light can get more attention from the car, but under the stimulation of strong light, it will create some unnecessary danger. This is why the lights are turned on at night instead of high light. The reason for the light. Many young people nowadays like to pursue their own personality and revise the color and position of the lights. It should be noted that the lighting position of the original factory can not be changed at will, and the decorative lights added later should also be careful not to be too close to the original position of the lights so as to avoid interference. Unsatisfactory conversions not only affect vehicle inspection and insurance, but also may cause traffic accidents that affect the sight and misjudgment of the incoming vehicle.

Finally, we need to pay attention to the different countries have different requirements for car lights. There are no rigid rules in the United States for turn signals and rear fog lights, but they are mandatory in China and Europe. For the front position lamp, the United States allows it to be white or yellow, and the regulatory requirements must be white. For riders who like to drive by themselves, it is necessary to understand these little knowledge.

Today, lights have become an integral part of the car itself. Everyone must pay attention to this "little eye" because it is not only the language of the car but also the security of the car.

A folding bicycle is a bicycle designed to fold into a compact form, facilitating transport and storage. When folded, the bikes can be more easily carried into buildings and houses or on public transportation (facilitating mixed-mode commuting and bicycle commuting), and more easily stored in compact living quarters or aboard a car, boat or plane.

Folding mechanisms vary, with each offering a distinct combination of folding speed, folding ease, compactness, ride, weight, durability and price. Distinguished by the complexities of their folding mechanism, more demanding structural requirements, greater number of parts, and more specialized market appeal, folding bikes may be more expensive than comparable non-folding models. The choice of model, apart from cost considerations, is a matter of resolving the various practical requirements: a quick easy fold, compact folded size, or a faster but less compact model.
