In recent years many local authorities across the UK have introduced part-night street lighting or dimmed their street lights at night in a move to control both costs and energy usage. This strategy has often been a cause for concern among residents within the communities affected though, with some believing that reducing street lighting during night time hours would lead to an increase in both road traffic accidents and crime levels.

However, a recent study by researchers from the London School of Hygiene & Tropical Medicine, could help to allay such fears. The observational study concludes that the researchers found little evidence of any negative effects on road collisions or crime of switching off or dimming street lights at night, introducing part-night lighting or changing to LEDs.

While it is essential to acknowledge that this is just one study, it is a valuable addition to the information available regarding this important subject. Click on the link here to view the full research report: http://jech.bmj.com/content/early/2015/07/08/jech-2015-206012.full.pdf
