Wildlife Warning System to Prevent Accidents on Road Sections with Frequent Wildlife Crossings


SWARO WARN, a visual wildlife warning device, was designed specifically to prevent accidents involving wildlife.

The headlight of an approaching vehicle is deflected by SWARO WARN WWR towards the roadside at dusk or night. This creates a constantly changing visual warning fence which prompts the wildlife to stop moving or to flee back into the countryside. The wildlife warning reflectors reflect the headlight towards the roadside only. There is therefore no risk of dazzling for the driver. Thanks to its innovative design, SWARO WARN WWR is well suited for any type of terrain. The fact that SWARO WARN WWR emits a wide cone-shaped beam of reflected light makes it suitable for use in flat and hilly areas alike. SWARO WARN WWR is an economical alternative to wildlife fences and smell barriers.

The materials used are resistant to environmental impacts, such as weather, road salt, high temperatures and exhaust fumes. SWARO WARN WWR is easy to install and clean.
