OUR JOURNEY
Growing from a specialist in LED traffic safety equipment into an integrated supplier of intelligent transportation hardware.
Dayu Optotech was established in Shenzhen, China, focusing on the research and manufacture of LED-based traffic safety lighting equipment.
We established an in-house R&D team and launched core products including variable message signs, variable speed limit boards, traffic signal systems, floodlights and tunnel lights.
Automated assembly, aging test and quality inspection workshops were upgraded to support growing overseas demand.
Our product range expanded to solar VMS, solar street lights, solar traffic signals, road studs, warning lights and solar signage, alongside OEM and ODM services.
Through overseas exhibitions and project experience, products reached Southeast Asia, the Middle East, Australia and Europe.
We strengthened aging, waterproof and high- and low-temperature testing, obtained CE and related certifications, and optimized quality control processes.
We continue to focus on renewable-energy traffic facilities and tailored solutions for international highway and tunnel construction projects.
