LIGHT SOURCES

Digital billboards, also known as Electronic Message Centres (EMCs), can be up to ten times brighter at night than traditionally lit billboards. Their intense illumination may cause glare, distract drivers, and even disrupt the behaviour of nocturnal wildlife by affecting their breeding, foraging, and orientation.
EMCs IN GERMANY
As shown on the map, illuminated displays are widely used throughout the city of Leipzig, Germany. To maximise visibility, these billboards are typically placed in high-traffic areas, especially near the city centre and in densely populated districts.
DIRECTIONAL LIGHTING
While the widespread presence of EMCs contributes to urban light pollution, a small mitigating factor is that many of these panels are designed to be illuminated from top to bottom. This approach helps ensure more uniform lighting and reduces direct glare. However, even with directional lighting, the overall brightness and visibility of EMCs remain a concern because of both environmental and public safety reasons.
