What potential consequence might arise from faulty lighting on a chassis?

The issue of faulty lighting on a chassis significantly impacts visibility, which can lead to accidents. Proper lighting is crucial for safe operation, particularly in low-light conditions or adverse weather. If the lights on a chassis are not functioning correctly, drivers may struggle to see the road, other vehicles, or potential hazards. This reduced visibility can dramatically increase the risk of collisions, resulting in accidents that could have been avoided with proper lighting.

In the context of the other options, while increased fuel consumption and higher maintenance costs could occur as a result of other issues in the vehicle systems, they are not direct consequences of faulty lighting. Fatigue for the driver may occasionally be linked to visibility issues, but the primary and most immediate risk associated with faulty lighting is indeed the potential for accidents. Thus, the most relevant and immediate consequence of such a malfunction is the safety risk posed to the driver and others on the road.
