Vehicle visibility is very important for road safety and for the reduction of road crashes. Emergency rear lighting systems significantly increase vehicle visibility but are limited, as they cannot be seen from a long distance and act exclusively parallel to the road axis. Present research demonstrates the validity of an innovative project able to transform a light into a lifesaving instrument. The project is based on the use in emergencies or during poor visibility driving conditions, of a colored lighting system, on a vertical axis, installed on the vehicle roof. According to a hypothetical point of view, the adoption of this innovative system ensures better visibility of the vehicle in all directions at long distance, and increases the safety of drivers and passengers. The system operates simply and its adoption does not represent a high cost so it can easily be implemented as best practice by vehicle manufacturers.
