The blue welcome light is very beautiful. Whenever the driver and passengers open the door to get on and off the bus, the welcome light will automatically light up in an instant and be projected onto the ground. Even at night, you can see it more conveniently.
When the door is closed, the welcome light will go out automatically. Its function is to make the car look more noble and elegant, and it can also be used to remind passers-by and vehicles to avoid unnecessary accidents.
