The broader cultural significance of public lighting(CLASSIC) as an integral part of modern (sub)urban life may also be closed, with some night lighting and dimming strategies linked to the crime. Residents and visitors may think that the area that reduces lighting has depreciated. This may reduce community pride and lead to behavioral changes that affect crime. Alternatively, the introduction of new technologies in a region, such as white light/LEDs, may indicate an increase in community investment in local residents, which may increase community pride and be willing to use and monitor their communities, thereby reducing crime.

In summary, streetlight adaptation strategies may have different effects on two public health outcomes, casualties, and crime. In view of the lack of evidence, we used local authorities in England and Wales to reduce public lighting as a natural experiment to check whether it was related to any changes in road traffic collisions and crimes.

In theory, street lighting adaptation strategies may affect the risk of road traffic collisions and crime in a variety of ways. Decreasing the level of illumination by turning off some nighttime illumination or dimming reduces the visibility of an area, which can increase the risk of collision if road users can no longer detect the danger. If you are worried about a collision, falling in the dark or fearing that crime will prevent people from making some journeys, then reduced visibility may also reduce mobility.
