To ensure **good visibility** while driving, it is essential that certain elements of the vehicle are in optimal condition. The **exterior rearview mirrors** and the **lighting devices** are fundamental for seeing what is happening around the vehicle and in low-light conditions, respectively.

- The **exterior rearview mirrors** allow the driver to observe the traffic behind and to the sides of the vehicle, which is crucial for safe maneuvers.
- The **lighting devices** are essential for seeing and being seen in low-light conditions or at night.

On the other hand, the **dashboard** does not directly contribute to the exterior visibility of the vehicle. Its main function is to provide information about the state of the vehicle, such as speed, fuel level, and other important alerts, but it does not help improve the visibility of the surroundings while driving. Therefore, the dashboard is not an element that helps provide good visibility inside the vehicle.
