Why is it important that decorative lights do not obscure required lights?

The importance of decorative lights not obscuring required lights primarily hinges on maintaining vehicle safety on the road. Required lights—such as headlights, brake lights, and turn signals—are essential for visibility and communication with other drivers. If decorative lights obstruct these necessary signals, it can create confusion and increase the risk of accidents. For instance, if brake lights are blocked, other drivers may not be aware of a vehicle's intention to stop, which could lead to rear-end collisions. Therefore, ensuring that decorative lights do not interfere with required lights is crucial for safe driving practices and protecting both the vehicle occupants and others on the road.
