To ensure the **proper use of vehicle lighting**, it is essential to review three key aspects: **adjustment**, **operation**, and the **condition of the system**.

- **Adjustment**: It is important that the lights are correctly adjusted to ensure they adequately illuminate the road and do not dazzle other drivers. This is crucial both at night and in low-light conditions, such as on dark days or when passing through tunnels.

- **Operation**: The lighting system must be in good working order. If any light fails while driving, it is necessary to reduce speed and use the lights that still work. You should not continue driving until the system is fully repaired.

- **Condition of the system**: The lamps that make up the lighting system should be checked regularly. If any lamp illuminates less than it should, it must be replaced to maintain adequate lighting.

Reviewing these aspects ensures that the vehicle is visible to other drivers and that the driver has good visibility of the road, which is essential for road safety.
