Siren Kits for Harley-Davidson add a distinctive, period-correct audible warning system to your motorcycle, whether for show or practical road use. Supplied through Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, our catalogue features siren kits from Samwel — a specialist in vintage Harley-Davidson reproduction parts. You will find mechanical siren units suitable for a range of applications, including Softail models from 1986–1999 and classic WL and Military machines from 1933–1945. Mechanical sirens were a hallmark of police and military Harley-Davidson motorcycles and remain highly sought after for period builds and show bikes. Each kit includes the mounting hardware needed for installation, and the mechanical design means no electrical connection is required — the siren is driven directly from a wheel or friction contact. Adding a siren brings authentic character and unmistakable presence to your vintage or custom build. Browse the full range below.
