LED car light means that the light sources inside and outside the car use LED technology for external and internal lighting. External lighting involves thermal limits and EMC issues, as well as many complex criteria for unloaded load testing. Car LED bulbs can be widely used to create a car interior environment, with a service life of 50,000 hours. The structure of the LED is sturdy and not easily affected by vibration, and the light output brightness will not drop significantly during use. http://www.glowteclighting.com/car-led-bulbs/
