[Arabella]

The function of the interior reading light is to provide illumination inside the vehicle. Below is a relevant introduction to car lighting: 1. LCD lights: Some LCD display instrument panels will automatically light up after the car is started, while analog gauge clusters will illuminate when the car lights are turned on. In addition to the instrument panel lights and interior dome lights, there are also glove compartment and trunk lights that automatically turn on when the respective compartments are opened. 2. Front and rear dome lights: The most commonly used interior lighting is the front and rear dome lights, also known as reading lights. There are buttons next to these lights, generally offering three modes: ON (constant illumination), DOOR (lights on when door opens, off when closed), and OFF (lights off). When set to DOOR mode, the lights will automatically turn on when the door is opened and off when it is closed.
