They also have high requirements on the details of the vehicles, and pay more and more attention to comfort and personalized experience.

[0003] In the prior art, vehicles are equipped with lighting for drivers and passengers in the cab. The lighting that comes with the original vehicle is generally a halogen lamp embedded in the interior panel of the vehicle body. Not only is it difficult to disassemble, but the lighting brightness of the halogen lamp is limited, making it difficult for the driver to find and operate the control buttons and functions in the vehicle, increasing the difficulty of operation and providing a poor user experience. For passengers, insufficient lighting will also affect their activities and experience in the vehicle, thereby affecting riding comfort. External LED lighting is installed in the vehicle. Since the angle of the LED lighting is not adjustable, it is easy for the light to directly hit the eyes of the driver or passenger, causing visual fatigue or glare problems.
