The function of the welcome lamp is mainly to show the luxury temperament of the vehicle. The pattern of the welcome light is mostly the logo of the vehicle, and related patterns can also be customized. When the door is opened, the welcome light will automatically light up, and after the door is closed, the welcome light will automatically go out. Now many models are equipped with welcome lights when they leave the factory, which saves the trouble of later modification.
The working principle of welcome lamp is that the light source projected by led refracts to the ground through the lens. According to the different colors of light bulbs, patterns of different colors can be projected. The welcome light is a device without noise and electronic interference, which will not have any impact on the use of vehicles, but will only improve the grade of vehicles and make them look more valuable.
