Dewalt Truck Horn

Engineered Loudness & Smart Protection

Our DeWalt truck horn combines a high-output air compressor, real metal train horn trumpets, and a custom control PCB that gives three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. The wireless remote reaches up to 2,000 feet and the unit accepts genuine DeWalt batteries (and other compatible tool-brand cells) for instant, cordless power. It’s built to sound like a true train horn while protecting both the motor and the battery during heavy use.

Ready-To-Use, No Installation Needed

The DeWalt truck horn arrives ready out of the box and runs off a compatible DeWalt battery for simple, tool-belt-style convenience. You’ll get instant, attention-grabbing sound for roadside alerts or ranch work, and it’s easy to move between trucks, UTVs, or job sites. Expect clear metal trumpet tones, quick charge swaps, and a compact footprint that won’t eat up storage space.
