What is the functional requirement for visible vehicle lights in terms of repairs?

The requirement for vehicle lights to be fully operational with no repairs is critical for safety and compliance standards in vehicle inspections. Vehicle lights are essential for visibility and communication on the road. They help inform other drivers of your intentions, such as turning or stopping, and are a key factor in preventing accidents, especially in low-light conditions. If the lights are not fully functional, it can significantly increase the risk of collisions, posing a danger not only to the driver but also to other road users.

This requirement ensures that any vehicle on the road meets the necessary safety standards and operates effectively. Only lights that are completely operational can provide the proper visibility and signaling needed for safe driving. Therefore, a vehicle with even partial functionality or minor repairs that do not restore full operational capability would not meet the required standards for safe use on public roads.
