What are the instructions for the headlight switch of the 2005 Buick Regal?

[SanRiley]

To operate the lights, ensure the vehicle is in the ignition-on state. The turn signals are controlled by the light control lever on the left side of the steering wheel, while the low beams, width indicator lights, fog lights, and other lighting functions are controlled by the light rotary knob on the driver's side of the center console. Here is some relevant information: 1. Trunk space: Trunk space is not the Regal's strong point. The capacity is only 441L, which is smaller than that of a mid-size car. The rear seats support a 4/6 split folding, but the floor is not level when folded down. However, this volume is sufficient for daily use. 2. Body information: The Regal has advantages in terms of length and width. Additionally, the difference in wheelbase affects the interior space, especially the rear seating area. The front features the Buick signature, with three metallic shield emblems embedded in the center. The three-dimensional combination headlights on both sides are equipped with corresponding '7'-shaped LED lights, which stand out more prominently than ordinary lights in dim lighting conditions.
