Dewalt Horn Gun

Engineered Performance & Practical Features

BossHorn’s Dewalt Horn Gun uses genuine DeWalt battery interfaces, a high-output air compressor, metal train horn trumpets, and our custom control PCB for three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. Hand-assembled in the U.S., the unit attaches to DeWalt batteries for cordless operation and includes wireless remote triggering up to 2,000 feet. The result is consistent, punchy sound with fail-safes that keep the motor and battery safe during repeated blasts and long sessions.

Ready-To-Use Portability

The Dewalt Horn Gun is instantly usable—just click a compatible DeWalt battery onto the unit and fire away. It’s ideal for flaggers, farmers signaling equipment, and event crews who need loud, directional sound without wiring or permanent mounts. Expect a compact, metal-bodied system that feels solid in hand, delivers immediate pressure build, and keeps working through long shifts.

Reliability You Can Rely On

BossHorn was first to make drill-powered train horns with long-range wireless remotes.

We use genuine cordless tool interfaces so the fit is perfect and dependable.

That craftsmanship means fewer surprises when you need maximum sound.

The Dewalt Horn Gun is built for dependability: it uses a DeWalt-compatible battery interface, an efficient compressor, and our PCB safeguards to prevent overheating and deep discharge. That combination gives sustained blasts, predictable motor behavior, and peace of mind on long job days or busy events—so you get loud, repeatable performance without fiddly setups.
