Heavy Duty Lighting

What Heavy Duty Lighting does

Heavy Duty Lighting (HDL) is a privately held, Portland, Oregon-based manufacturer of LED lighting solutions purpose-built for the heavy-duty commercial vehicle market. Founded in the 1990s and LED-only from inception, the company designs, sources, and markets a broad catalog of clearance markers, work lights, stop/tail/turn lights, light bars, warning/emergency lighting, electronic flashers, and OEM-specific direct-fit lighting for platforms including Mack Anthem, Kenworth T600/T300, and Peterbilt 387/388/567/587. Core technical differentiation centers on proprietary ColorFlux™ dual-color, color-changing technology (powering the DualShift™ Series clearance markers) and the Advanced Temperature Control System (ATCS®), which allows LEDs to operate at higher lumen output without compromising longevity; products are also built around impact-resistant polycarbonate lenses, stainless steel bezels, conformally coated electronics, and IP67/IP69K sealing. Manufacturing is outsourced to multiple ISO-9001 and ISO/TS 16949 certified partner facilities, giving HDL an asset-light cost structure with the flexibility to scale with industry cycles.

HDL operates a B2B go-to-market motion with no direct-to-consumer sales. All products flow through a North American network of independent manufacturer's representatives organized by US state, Canadian province, and Mexican state, then onward to vetted stocking distributors, dealers, and OEMs. An Online Service Center (portal.nowcommerce.com) supports existing channel partners with order placement, invoicing, and account management. The company serves heavy-duty trucking fleets, trailer manufacturers and operators, RV makers, and off-highway/construction/agricultural equipment operators across the United States, Canada, Mexico, Central America, the Caribbean, and South America. End customers contact HDL by selecting their region on the company website to be routed to the local sales representative. Pricing is not publicly disclosed, and revenue is generated through hardware sales of LED lighting units and accessories. The company is independently operated with no disclosed institutional investors, parent entity, or acquisition activity, has 11–50 employees, and no funding rounds have been disclosed in the source material.
