Russia Unveils Ultra-Efficient Smart Traffic Light at INNOPROM-2025

The new DS7-Light traffic signal consumes 2.5 times less power while maintaining brightness and reliability, and is ready for mass production.

At the INNOPROM-2025 international expo, Russian tech giant Shvabe, part of the Rostec conglomerate, introduced the DS7-Light — a next-generation traffic signal that promises a dramatic boost in energy efficiency, durability, and road safety. The product has already been certified and is slated for production and delivery later this year.

Weighing just 3 kg for pedestrian versions and 4 kg for vehicle signals, the DS7-Light is about half as heavy as existing models. Thanks to modern materials and a custom polymer housing developed by the Ural Optical and Mechanical Plant, it uses 2.5 times less energy without compromising brightness. It also meets Customs Union standards and can function in extreme conditions ranging from −50 to +60°C, with resistance to UV radiation and electromagnetic interference.

One of its standout features is an RS-485 digital interface, enabling seamless communication with road controllers. This ensures synchronization across intersections and prevents conflicting signals.

Russia’s broader push for smart traffic infrastructure is already delivering results. In Perm, adaptive traffic lights have cut vehicle delays by 60 percent, while a unified traffic management platform enables fast response to accidents and roadwork.

“These solutions optimize traffic flow and lay the groundwork for smart city development, including autonomous vehicle technologies,” said Taras Koval, president of the Association of Transport Experts.
