With regard to the story of car history, it is not difficult to see the beginning: a long time ago, cars did not have lights. It is said that the first car headlights are household hand lamps. In the middle of the night when the fingers were not visible, a farmer took the lost driver home with a portable light.

In 1898, Boston hosted the first American automobile exhibition. The American Columbia car used electric lights as headlights and taillights, and the lights were born. In 1916, a man named C.H. Thomas in the United States put a light bulb with a battery on his glove in order to let the other driver see his gesture at night, and the turn signal light came on stage.

In 1938, the American Buick was equipped with a steering flash, which was only installed as an optional accessory at the rear of the car. It was not until 1940 that the turn signals were installed in the front of the car. The idea has returned to the present from a distant era. With the development of automobile technology, the crystal magic stone like cultivating for many years has become more and more beautiful. Early car headlights used tungsten incandescent lamps, and dim light could only be supplied to slower cars. For a long time, incandescent lamps have been the main source of light for various types of lamps in the domestic market. Due to the unstable quality of incandescent lamps, many car accidents occur every year in China, and incandescent vacuum lamps are gradually being phased out.

Halogens for automotive lighting have gained popularity in the last 20 years. Each light of a halogen lamp consists of two sets of filaments. One group is the main beam filament, and the emitted light is reflected directly by the lampshade mirror. This kind of light is what we call "high beam". The other is a partial beam filament, which emits light to the visor to the upper half of the reflector mirror. The reflected light is diffused downwards to the ground, causing dizziness to the driver who is on the opposite side. This kind of light source is what we call "low beam". A disadvantage of halogen lamps is that their luminescence ability is gradually degraded after a period of use. Therefore, many motorists use a special size bulb to increase the luminous intensity to meet the needs of night driving. The disadvantage of this type of bulb is that the power consumption is too large, and the heat generated by the bulb is also large, so that the glass of the lamp housing is broken, or the reflective coating in the lamp housing is peeled off due to thermal expansion, and even cracks and deforms.

Modern cars emphasize safety and comfort. Car anti-skid braking systems and airbags are used in almost all cars, but there are still many accidents that occur under harsh visual conditions, such as night and bad weather. And as the average age of drivers increases, older people need six times more illumination than young people while driving, all of which place higher demands on lighting.

After entering the 21st century, automotive lighting has entered a new era. Philips has successfully developed a xenon lamp for 5 years, referred to as HID (High Intensity Discharge Lamp), and is the first to be equipped in a European premium sedan. The xenon lamp lighting system consists of 3 matching parts. A miniature gas discharge lamp acts as a light source, an electronic device controls the start and ignition points, and a finely matched front lighting fixture. The main difference between a xenon lamp and a halogen lamp is that the former emits light by gas ionization, and the latter emits light by heating tungsten wire. The high reliability of the xenon lamp is not affected by the voltage fluctuations on the car, which improves the safety of driving at night. Since the filament is not used, there is no problem that the conventional filament is brittle, and the service life is much longer than that of the ordinary halogen lamp. In addition, the smaller headlamp volume gives the car a more creative space for exterior design, and automakers benefit from the ability to use low-temperature plastics and reduce energy consumption. Therefore, xenon lamps have gradually become the mainstream trend of modern car lights.
