For a car, the lights are like its eyes, and nowadays energy-saving, environmentally friendly, and smaller LED lights have become a popular element in decorating your car. For example, LED headlights, LED brake lights, LED reversing lights, LED strobe lights, LED daytime running lights, etc. , are favored by young car owners. For automobile manufacturers, they are now also beginning to extend from only assembling LED lights for medium models to low-end models, such as Guangqi Honda lingpai, Dongfeng Fengshen new S30 and other models, this move has undoubtedly improved the selling point of the product. Although LED lamps are more dazzling and cool, their maintenance cost is really expensive compared with traditional lamps. If the owner modifies it himself, he should also pay attention to whether the annual inspection is qualified and whether the wire harness is thick enough, don't leave hidden dangers for car use and driving safety. The LED lights that dazzle the eyes of young consumers have now become a major concern for consumers when buying cars, especially for young consumers, who will ask when buying cars. Sun Guangji, marketing manager of Yongcheng 4S store in Jilin, Dongfeng Fengshen, told reporters that LED daytime running lights have begun to become civilian, which can only be seen on Audi, BMW, imported Volkswagen and other models, many cars running on the road are now equipped. However, for many young car owners, the use of LED daytime running lights is now more than a trend, not a trend. My whole set of lights have been replaced with LED lights, including brake lights, headlights, turn signals, daytime running lights, etc. 90 after the owner Xiao Liu said with a smile. Mr. Wang, a modified enthusiast of the New Culture Newspaper Cheyou Club, said: in fact, in addition to cool, the modified LED lights can also ensure driving safety, for example, vehicles modified with LED daytime running lights can be more recognized by other vehicles in the case of glare of sunlight during the day or poor visibility in rainy and foggy days. Once the repair cost is not low, the LED lights are dazzling, but their high maintenance costs make the car owners can't afford to hurt. According to boss Zhao of Changchun Auto Trade City auto parts store, the appearance of LED lamps is not only dazzling, but also the brightness of LED headlights exceeds that of xenon headlights, which makes the lighting reaction speed fast, but the price is relatively high, for example, LED headlights for luxury models such as Mercedes-Benz and BMW are priced at 20 thousand ~ 80 thousand yuan is not a small burden for car owners. Recently, the car friend Xiao Song is annoyed for the maintenance cost of his car. The reporter was informed that the LED turn signal of a luxury brand car driven by Xiao Song was broken, and it was found to be burnt out when it was sent to the 4S store for maintenance. Originally, I thought it would be OK to replace a light bulb for several hundred yuan, but the maintenance worker told me that this LED turn signal cannot replace the light bulb alone. If it breaks down, I need to replace the whole assembly. The price is about 2000 yuan. Xiao Song said helplessly. Mr. Zhao, the owner of a joint venture brand, has the same experience as Xiao Song: my LED brake light is off, I went to the 4S store and asked for an assembly, the cost is nearly 1500 yuan, the price quoted by the repair shop outside is also over 1,000 yuan. Think about it, it is still cheap for ordinary halogen bulbs! It is understood that many car owners like DIY cars at present, among which there are not a few young car owners who modify LED lights by themselves, but there are many matters needing attention when installing LED lights by themselves. Liu Ying, director of the after-sales service department of GAC Toyota Chengbang 4S store, said: The LED lamp is actually a light-emitting diode, which is a light source with one-way conduction, longevity, power saving, low heat and low voltage. When selecting LED lamps, special attention should be paid to the thickness of wiring. It is recommended to select a thicker wire harness, which can ensure that it is not easy to be burnt out during use, and at the same time, attention should be paid to the concealment of wiring during installation, don't expose too much to the outside to avoid leaving a safety hazard. In addition, the main factor affecting the light efficiency and service life of LED lamps is temperature, so it is recommended to select LED lamps with good thermal conductivity for owners who want to modify LED lamps, and pay attention to the heat dissipation environment of the surrounding environment of the LED lamp in the future during the installation process. It is worth mentioning that the modified owner must not destroy the appearance of the original car. Once the appearance is changed, there will be trouble during the annual inspection.
