What should be included in a comprehensive inspection of the lighting devices?

Answer: A — Headlights and brake lights

A comprehensive inspection of lighting devices should include headlights and brake lights because these components are crucial for vehicle safety and visibility. Headlights ensure that the driver can see the road and be seen by others during low-light conditions. Brake lights are essential for signaling to other drivers when the vehicle is slowing down or stopping, helping to prevent rear-end collisions. In a thorough lighting inspection, it's important to check not just that these lights turn on, but also that they are adequately bright, properly aligned, and free of any physical damage. This process ensures that all lighting functions meet safety regulations and contribute to safe driving conditions. The inclusion of headlights and brake lights is fundamental to the overall effectiveness of the vehicle’s lighting system.
