On February 8, 2026, drivers entering Gladsaxe, just outside Copenhagen, were greeted by a striking sight: a busy road painted in a deep red glow. Frederikborgvej looked almost surreal, as if someone had laid a red filter over the street. The change is a targeted attempt to cut light pollution while keeping the road usable for people. The road covers the path of a known bat corridor. The familiar bright white LED streetlights have been replaced by red LEDs. The red LEDs paint the pavement and nearby trees with a deep red glow. The goal is to allow bats to pass through safely and to reduce light pollution. This comes in the wake of a pressing issue of light pollution affecting human sleep patterns and disrupting nocturnal wildlife.

I think the real challenge will be getting people to adapt to the new lighting. Change can be hard, even when it's for a good cause.. Red lights might look cool but they could be less noticeable and harder to read maps in!

This is amazing! Finally, a solution that considers both wildlife and human needs.

I live near a bat colony and I've noticed how bright lights disrupt their flight paths. This could really help in areas where bats are common. The red lighting could help reduce their stress and allow them to navigate freely. It's a win-win for both humans and wildlife. Plus, it's a creative way to reduce light pollution without compromising safety.

We've seen similar initiatives in other European cities, and they've been pretty successful. It's great to see Denmark taking this step. The red lighting is a great way to balance the needs of both wildlife and humans.

I wonder how they chose the specific shade of red. Was it based on scientific research or just trial and error?

Imagine driving down a red-lit road at night. It's like a scene from a sci-fi movie! I have no idea how safe this is for drivers.

I think it’s a great initiative. The red glow looks more dramatic. It could be a tourist attraction for the town. It's not a night show it's just a town

The red lighting is designed to be less disruptive to nocturnal animals like bats. It's a clever solution that addresses multiple issues. Red light is less likely to penetrate the trees and plants and disturb the ecosystems of birds and bugs that make their homes in the canopy. Red light is also less likely to make the town look like a light show and attract more man like traffic. A town that is well lit at night will attract crimes

I'm not sure how effective red lights will be. Won't bats still avoid the road due to human presence?
