What indicates that a light must be attended to before a vehicle inspection?

A light must be attended to before a vehicle inspection if 50% or more of its components are non-functional. This is important because a significant portion of the lighting system being faulty can greatly affect visibility and safety on the road. In Maine, like in many other places, proper functioning lights are crucial for vehicle safety, as they ensure that the driver can see, and others can see the vehicle at all times, especially in low-light conditions.

While factors like flickering, dimness, or color changes can indicate potential issues with the lights, they are not as critical as the overall functionality of the entire lighting system. If the majority of a light's components are not working, it is a clear sign that the vehicle is not safe to operate and requires immediate repair before it can pass inspection. Maintaining proper lighting standards is essential for avoiding accidents and ensuring compliance with safety regulations.
