Grote Industries is marking its 125th anniversary this year, underscoring more than a century of innovation that has helped shape commercial vehicle lighting, wiring and safety systems.
Established in 1901 by William D. Grote as a chemical and industrial oxygen manufacturing company, the business quickly evolved alongside the transportation industry. By the 1920s, Grote was producing the nation’s first injection-molded plastic products and later developed the first fully automatic plastic injection-molding machine. In 1929, Grote created the first retro-reflective vehicle reflector, a breakthrough that became the universal basis for reflectors seen on the roads today, and helped define Grote’s long-term focus on vehicle safety systems.
For generations, Grote Industries has been shaped not only by innovation but by the people who built their lives around it. Bill Grote, current Chairman of the Board, recalled growing up in the family’s home. Dinner was always at six, Bill remembered, describing how every child learned discipline, responsibility, and the value of showing up. These same family principles continue to guide the company every day.
Over the decades, Grote continued to introduce industry “firsts” designed to solve real-world fleet challenges. These include the industry's first all non-metallic lamp, the Turtle-Back® Marker Lamp (1965), the industry's first no-splice wiring system (1965), the world's first modular trailer wiring system, Ultra-Blue-Seal® (1983), and the industry’s first LED marker light (1989). Each advancement reflected the company’s emphasis on durability, simplified installation and improved long-term performance.
This tradition of innovation continues today with the company’s evolution into the smart trailer category with Grote’s Networks division and 4SEE®, providing customer-focused solutions through advanced technologies such as programmable lighting, radar, and integrated telematics to improve Fleet safety and operational efficiencies.
“For 125 years, our success has come from standing shoulder‑to‑shoulder with our customers,” said Dominic Grote, Chief Executive Officer. “We listen first, innovate second, and measure every advancement by how well it addresses real challenges our customers face. That commitment – to partner deeply, respond quickly, and design with purpose - continues to guide every new product we create at Grote Industries.”
While its technology has evolved, Grote has remained family-owned throughout its history – continuity that has shaped its long-term approach to growth and customer relationships.”
“What I’ve always been proudest of is that Grote grew the right way – by doing things honestly, treating people fairly, and never being afraid to take a chance when the opportunity was right,” said Buzz Grote, past Chairman of the Board. “When we were first experimenting with LED lamps, we took the idea straight to one of our fleet customers, and their response was simple: ‘If you can build something like that, I’d buy it.’ That trust and confidence meant everything, and it’s that same partnership with customers that has driven Grote’s success ever since.”
In recognition of its 125th anniversary, Grote will host companywide celebrations throughout June, bringing employees across the globe together to commemorate the milestone and reflect on the company’s continued role in advancing transportation safety.
Headquartered in Madison, Indiana, Grote now operates in New York, Canada, Mexico, Germany, and China. More than 1,600 employees work in every phase of production, from design and engineering to manufacturing, testing, marketing and distribution.
From 1901 to the present, Grote Industries continues to focus on the values that William D. Grote inspired: safety, quality, and innovation. This provides the foundation for advancing visibility, electrical and intelligent trailer systems that help fleets and manufacturers navigate the next era of commercial vehicle innovation.
