Auto LED lamp, lamp is lighting and signal. The lamp light can illuminate the road in front of the car, so the driver can in the night driving safety, according to the current source can be divided into: halogen lamp and xenon lamp, but there are a few defects:1, the halogen light flux is 1300LM, the lighting is dim, irradiation distance is short, affecting the traffic safety.2, although the xenon lamp light, but the starting time in 3-8 seconds, in the light of overtaking, too long, tens of meters in the dark area, affecting the traffic safety.3, halogen lamp and xenon lamp lighting luminous efficiency is low, power consumption, long lights seriously affect the battery life, even electricity can not start the car.4, halogen lamp xenon lamp had low brightness, color temperature is difficult to control, low visibility in foggy weather.5, halogen lamp use life in 400 hours, xenon lamp is normal in 2000 hours, life is relatively short, the owners have to replace the light bulbs, the cost is relatively high.6, xenon lamp 23000V instantaneous voltage is easy to cause the vehicle circuit system disorders, serious or even burn the car, the car is difficult to decode the high-end.7, mercury is a heavy metal, easy to cause environmental pollution
