What must headlights demonstrate during inspection?

1. Correct alignment and sufficient brightness

2. Self-adjustment according to speed

3. Being fully transparent and undamaged

4. Ability to turn on and off automatically

The correct answer is: Correct alignment and sufficient brightness

Headlights must demonstrate correct alignment and sufficient brightness during an inspection to ensure safe operation of the vehicle. Proper alignment is crucial because misaligned headlights can blind oncoming drivers or fail to adequately illuminate the road ahead, creating a hazard. Sufficient brightness is equally important; headlights that are too dim can significantly reduce visibility at night or in adverse weather conditions, compromising safety. While other options may describe desirable characteristics of headlights, they do not encompass the fundamental requirements for inspection. For instance, self-adjustment according to speed is not a standard requirement, as most vehicles do not feature this capability. Additionally, complete transparency and being undamaged is important, but these factors alone do not ensure that the headlights are functioning correctly in terms of alignment and brightness. Similarly, although the ability to turn on and off automatically might be a modern vehicle feature, it is not a critical aspect inspected for compliance with basic safety standards.
