Daylighting Wildlife Tunnels: A Proven Solution for Safer Wildlife Crossings
Natural daylight for wildlife tunnels, underpasses and ecological corridors
Techcomlight continues to improve the safety and effectiveness of wildlife tunnels, wildlife underpasses, animal tunnels, ecological crossings and other wildlife crossing structures with the Dutch-made Powerdaylight® tubular daylighting system.
For decades, tubular daylighting systems have been used to transport natural daylight deep into wildlife tunnels, creating brighter, more inviting passages for animals. With the Powerdaylight® daylight tube, Techcomlight continues this proven concept using a system that is manufactured and assembled in the Netherlands and supplied fully customised for every project.
Why natural daylight matters in wildlife tunnels
A wildlife tunnel is only successful if animals are willing to use it. Natural daylight plays a crucial role in encouraging safe animal movement.
Many species instinctively move towards light. In long or enclosed wildlife underpasses, dark sections can discourage animals from continuing, causing them to turn back. Introducing natural daylight into the tunnel creates visible light further along the passage, giving animals confidence to continue safely through the crossing.
By transporting daylight from the surface into the tunnel using the Powerdaylight® tubular daylighting system, the tunnel becomes brighter, more natural and significantly more attractive for wildlife. This helps increase tunnel usage while strengthening ecological connectivity between habitats.
Applications
The Powerdaylight® daylight tube is suitable for a wide range of wildlife infrastructure, including:
- Wildlife tunnels
- Wildlife underpasses
- Animal tunnels
- Wildlife crossings
- Ecological crossings
- Green corridors
- Ecological corridors
- Mammal underpasses
- Amphibian tunnels
- Frog tunnels
- Toad tunnels
- Badger tunnels
- Otter tunnels
- Wildlife passages beneath roads, motorways and railway lines
Key Benefits
The Powerdaylight® system offers numerous advantages for wildlife infrastructure projects:
- Brings 100% natural daylight into wildlife tunnels without electricity.
- No energy consumption and no lighting maintenance.
- Creates a brighter, safer and more natural environment for wildlife.
- Delivers daylight deep into long wildlife tunnels and underpasses.
- Encourages animals to use wildlife crossings more confidently.
- Supports ecological connectivity between fragmented habitats.
- Improves the effectiveness of wildlife corridors and ecological networks.
- Suitable for amphibians, mammals and a wide variety of wildlife species.
- Available in multiple diameters to provide the correct daylight level for every tunnel design.
- Prefabricated systems for fast and efficient installation.
- Fully customised in diameter, length and configuration.
- Suitable for both new construction and refurbishment of existing wildlife tunnels.
- Manufactured from corrosion-resistant materials for long-term performance in damp environments.
- A sustainable solution supporting climate-resilient and circular infrastructure projects.
- Low Total Cost of Ownership (TCO) thanks to long service life and minimal maintenance.
- Available with multiple external finishes to suit different project requirements.
Designed for Every Wildlife Crossing Project
Every wildlife crossing presents unique engineering challenges. That's why Techcomlight supplies both standard products and fully bespoke solutions.
For installations alongside roads and embankments, we recommend our impact-resistant polycarbonate dome, installed slightly above ground level to reduce the risk of damage during grass cutting and routine maintenance.
Depending on project requirements, additional options include:
- Walkable surface finishes
- Drive-over systems suitable for maintenance vehicles
- Custom connections for precast concrete structures
- Bespoke solutions for highways, rail infrastructure, local authorities and national road agencies
Fast Installation Minimises Traffic Disruption
Infrastructure projects demand efficient construction and minimal road closures.
Thanks to our prefabricated systems, Powerdaylight® daylight tubes can be installed quickly into both new and existing wildlife tunnels. Faster installation reduces construction time, minimises lane closures and improves safety for contractors, road users and maintenance teams while reducing disruption to tr
