DIY Train Horn Gun Kit with Remote (Universal) - up to 140db

Picture the payoff. The trumpets are bolted on, the harness is wired, the battery clicks home — and from across the lot you press a small remote and four trumpets erupt at up to 140 dB — an impact you feel as much as hear. That is what an afternoon of wrenching gets you with the DIY Train Horn Gun Kit with Remote: a universal, build-it-yourself horn gun that runs on the drill you already own.

• Up to 140 dB of output — louder than nearly any stock vehicle horn
• Quad-trumpet setup for that unmistakable deep train-horn voice
• Wireless remote included, with up to 160 ft of standard range
• Fits most brushed and brushless drills — no single brand required
• Pre-built wiring harness with the remote receiver already integrated
• Optional Extreme Trumpets upgrade available at checkout for a bolder blast
• Available in black, chrome, or red

Why Pick the Remote Version?

In our universal DIY lineup, this is the full package. Where the base kit is trigger-only, this one adds a wireless remote and a receiver harness that arrives pre-built, so the trickiest wiring is already done before you open the toolbox. It also widens your options on the donor tool: brushed or brushless, most drills will do. If you are shopping for a tinkerer — or you are the tinkerer — this is the version that keeps surprising people long after the build is done, firing on command from up to 160 ft away.

The project itself is satisfying, hands-on work: strip the drill shell, mount the compressor, land the harness on the terminals, test, close it up, and bolt on the horn. The included guide walks each step, and the finished horn is a cordless, battery powered, tank-free noisemaker you can carry to game days, campouts, and celebrations.
