About Signaltone/FIAMM: A Global Leader in Acoustic Signaling

FIAMM — marketed in North America under the Signaltone/FIAMM name — stands as one of the world's most recognized manufacturers of automotive acoustic signaling devices. With roots tracing back to Italy in 1942, FIAMM has spent more than 80 years engineering horns and signaling systems that are trusted by vehicle manufacturers, commercial fleets, and everyday drivers alike. What started as a battery company evolved into a global acoustic powerhouse, with a dedicated division — FIAMM Components Accessories (FCA) — focused entirely on horn and signaling technology for the automotive and beyond.

Engineering Sound Safety Across Every Vehicle Type

Few brands can claim the breadth of application that FIAMM covers. Their acoustic devices serve motorcycles, passenger cars, light trucks, commercial vehicles, heavy industrial machinery, public transportation, and marine vessels. Whether you're driving a compact car or operating a fleet of delivery vans, FIAMM has engineered a signaling solution built for the demands of your application. That versatility is backed by manufacturing facilities on multiple continents, rigorous international quality certifications, and a long track record as an OEM supplier to major automakers — earning supplier recognition from companies such as Caterpillar, Ford, and GM.

The Signaltone/FIAMM catalog spans electromagnetic, electropneumatic, electronic, and air-powered designs, giving buyers and technicians the flexibility to match the right horn to the right platform. Many of these products are built to meet both SAE and CE specifications, making them legal for road use and dependable under constant duty cycles.

Core Product Categories

Signaltone/FIAMM's strength runs across several key signaling categories. Their lineup of Horns forms the heart of the brand — from disc-style electromagnetic units for passenger vehicles to high-pressure air horns for trucks and RVs. For drivers looking for a direct OEM-style replacement or an upgrade, their Electric Horns deliver clean, reliable sound from a compact, corrosion-resistant housing. Fleet and commercial operators will appreciate FIAMM's line of Back Up Alarms, engineered for trailers, forklifts, buses, and delivery vehicles with steam-cleanable, polarity-protected construction. When a complete installation is the goal, the Horn Kit offerings bundle horns with compressors and relays, giving technicians everything needed in a single package.

Innovation for the Modern Era: AVAS Technology

As electric and hybrid vehicles continue to reshape the automotive landscape, FIAMM has positioned itself at the forefront of next-generation acoustic safety. Their Acoustic Vehicle Alerting System (AVAS) technology — now mandatory on all new silent vehicles since 2019 — provides fully customizable warning sounds that alert pedestrians to otherwise silent EVs at low speeds. This forward-looking approach demonstrates that Signaltone/FIAMM is not just a legacy horn brand, but an active innovator in vehicular safety technology.

A Brand Built on Trust

Signaltone/FIAMM products are a dependable choice for workshops, fleets, and enthusiasts who need signaling devices that perform in demanding conditions without constant maintenance. Their global distribution network and deep OEM relationships ensure consistent quality and broad parts availability, making them a go-to name whether you are replacing a worn factory horn or upgrading for improved performance.
