About Jammy, Inc.

Jammy, Inc. is a U.S.-based manufacturer specializing in vehicular lighting, electrical components, and precision metal fabrication for a wide range of industries — from automotive and trailer hauling to RV, marine, off-highway, and agricultural equipment. With a product line built to withstand demanding real-world environments, Jammy has earned a reputation as a dependable OEM and aftermarket supplier trusted by fleet operators, tradespeople, and equipment owners alike.

Lighting Built to DOT and SAE Standards

At the heart of Jammy's catalog is an extensive lighting lineup covering virtually every application where a vehicle tows or can be towed. All Jammy lighting is photometrically tested to meet or exceed SAE/DOT specifications as set forth in FMVSS 108, with testing conducted at fully accredited stateside laboratories. The range includes LED clearance and marker lamps, stop/turn/tail lamps, work lamps, LED light strips, and complete trailer light kits — all engineered to integrate seamlessly with standard grommets, brackets, and wire harnesses.

Jammy's LED line stands out for its use of modern SMD diode technology and is backed by a lifetime warranty against defects in materials or workmanship on most products. The incandescent line carries a standard three-year no-hassle warranty. Whether you're retrofitting an existing setup or outfitting a new build, Jammy's LED and incandescent products share the same mounting hardware — eliminating the need to source additional parts for upgrades.

Electrical Components and Trailer Accessories

Beyond lighting, Jammy manufactures a broad range of trailer electrical components including 4-way, 5-way, and 7-way wiring harnesses, plugs, and junction boxes to get power reliably to your equipment. Their breakaway systems — such as the J-BWEK series — feature integrated LED charge indicators, built-in charging circuits, and heavy-duty battery boxes designed for long-term reliability in demanding conditions.

Jammy's reflectivity product line adds another layer of safety, offering conspicuity tape in multiple grades, Class A reflex reflectors, warning triangles, and other safety marking equipment — all certified to exceed DOT/SAE specifications.

Precision Metal and Custom Fabrication

Jammy rounds out its offering with a line of precision metal components and trailer accessories that span everything from bar locks and door parts to brackets, bumpers, seat hinges, handles, and tie-downs. Serving RVs, grain carts, and heavy equipment alike, Jammy also offers custom design and production services for metal and injection-molded parts — making them a versatile partner for OEM applications and specialty builds.
