What type of headlight bulb is BMW X6?

The headlight bulb model of BMW X6 is imported D3S, and the domestic model is D1s. Car headlights, also known as headlights and LED daytime running lights, as the eyes of a car, is not only related to the external image of the owner, but also closely related to safe driving at night or in bad weather conditions.

What is the most important electrical appliance in a car? There is no doubt that it is a lamp. Car headlights classification: 1. Halogen lamp The bulb of this lamp contains halogen substances such as iodine, which sublimate into tungsten filament at high temperature. After cooling, tungsten will solidify on the tungsten wire, which has a long service life, but its structure is relatively simple and its price is cheap. It has strong penetrating power, even light. The disadvantage is that the halogen lamp has extremely high temperature, limited brightness, yellow light, belonging to warm light, and the brightness may not be bright enough. However, when taking dirt roads and cement roads, especially in towns and villages in the urban-rural fringe, the brightness is still very high, but when facing the black road, it is insufficient. 2. Xenon headlights In the 1990s, Haila, a professional car lamp manufacturer, introduced mature xenon headlights to the market. Xenon lamp broke the principle of tungsten filament light-emitting invented by Edison, replaced the traditional filament with high-pressure inert gas, and excited xenon light-emitting with high-voltage current of 23,000 volts, forming a perfect white arc between the two poles. Xenon lamps have three times the brightness, half the energy consumption and seven times the service life of halogen lamps. Simply put, as long as there is no man-made damage, there is no need to replace the headlights within the service life of the vehicle for more than ten years. However, the xenon headlights just applied will cause glare to the opposite driver, which poses a safety hazard. Later, the automatic adjustment of headlight height was applied to solve this problem. 3. The Chinese name of LED headlight LED is light-emitting diode, which was first used in Audi R8. Audi has also won the reputation of "lighting factory" because it has brought LED headlights to a new height. Compared with previous light sources, LED headlights are brighter and more energy-saving, and there is no delay in lighting xenon lamps. It is important that a single LED emitter is small in size and can be combined into different shapes, and because it can emit light independently, it can better control the shape and position of the light beam. Therefore, the application of LED headlights has truly realized the intelligence of car headlights. 4. Laser headlights Laser headlights are the most "tall" light source at present, and the scientific name is "laser diode". Originally, it has something in common with LED. It has all the advantages of LED lamps, and it is more energy-saving, brighter and smaller than LED, which is more convenient for designers to "concave shape" on headlights. But the cost of laser headlights is the highest among all light sources. At present, it is only used for high-end luxury models, such as Audi R8, new A8 and BMW 7 Series. It will take time for laser headlights to become as popular as LED lights.
