About Grote Industries

Grote Industries has been at the forefront of vehicle visibility and safety for well over a century. Founded in 1901 by William Grote in Madison, Indiana, the company began as a small operation that quickly pivoted toward the booming automotive industry. What started as a family venture has grown into a globally recognized, family-owned manufacturer with facilities in the United States, Canada, Mexico, Europe, and Asia — yet the Grote family remains actively involved in the business to this day.

Grote's history is a timeline of industry firsts. The company introduced injection-molded plastic products to the marketplace in the 1920s, developed the world's first retro-reflective reflector in 1929, and engineered the industry's first all non-metallic lamp. In 1980, Grote brought the world's first modular trailer wiring system — the Ultra-Blue-Seal® — to market, and in 2004, Grote was the first manufacturer to put LED forward lighting on American roads. This unbroken legacy of innovation reflects a company deeply committed to making vehicles safer and more visible.

What Grote Makes

Grote's product portfolio is broad but purpose-driven, centered on lighting, electrical systems, and visibility components for heavy-duty trucks, trailers, vocational vehicles, agricultural machinery, military equipment, and more. The lineup spans LED, fluorescent, and incandescent interior and exterior lamps; stop, tail, and turn signal lighting; power delivery and wiring solutions; mirrors; reflectors; connectors; and safety accessories. Whether the application is an over-the-road semi, a utility trailer, or an off-highway machine, Grote offers an integrated system approach — meaning fleets and OEMs can source their entire electrical and lighting infrastructure from one trusted supplier.

Among Grote's most in-demand product lines are its door mirror kits, engineered to deliver clear rearward visibility on commercial and vocational vehicles. Grote also carries a robust selection of engine wiring harnesses, part of a comprehensive power delivery family that includes nose boxes, pigtails, adapters, and the legendary Ultra-Blue-Seal® sealed harness system. And for anyone outfitting or replacing lighting on a boat, utility, or commercial trailer, Grote's trailer lights are a go-to choice — backed by decades of engineering expertise in rugged, long-life illumination.

Why Technicians and Fleets Trust Grote

Grote was the first manufacturer in its industry to earn TS16949 certification, underscoring its commitment to quality management at every stage of production. Rigorous environmental testing, close collaboration with OEM distributors, and a genuine responsiveness to fleet managers' real-world needs have helped Grote maintain its competitive edge for generations. Whether you're a professional technician sourcing replacement parts or a fleet manager outfitting a new vehicle, Grote's depth of catalog and reputation for durability make it a reliable first choice.
