Lumin8 delivers innovative traffic signal, lighting, and Intelligent Transportation Systems (ITS) services and solutions across the country.

Headquartered in Arvada, Colorado, Lumin8 was formed in July 2020 through the acquisition and merger of leading companies in the traffic signal and ITS service industries: W.L. Contractors (“WL”), Carlson Construction Services (“Carlson”), Wilburn Engineering (“Wilburn”) and, most recently in December 2021, the integration of all the assets of Digital Traffic Systems (DTS).

The combined business represents one of the largest providers in the industry. Lumin8 boasts operational facilities across the country and over 350 employees, serving local, state, and federal government entities, agencies, and contractors throughout the United States.


We are committed to providing the highest level of support and quality to our customers by maintaining ITS and traffic signal assets with the best operations, reliability, and availability.

We value the long-standing relationships we have with our customers. With that in mind, we strive to deliver Service Beyond Expectations by meeting and exceeding the customer needs and requirements for each project.

We provide training, equipment, and tools to ensure a safe and healthy work environment for all our employees – to minimize the possibility of injury to our teams and the public as a result of our operations.
