Frequently Asked Questions

Do the DeWalt Train Horns include an actual drill or just the horn setup?

Every DeWalt Train Horn is handcrafted from a brand-new DeWalt 20V MAX impact driver. The horn is fully assembled and ready to go—no additional tools or modifications required. Just attach a battery and blast away.

How powerful is the sound produced by a DeWalt Train Horn?

Extremely loud! All DeWalt models deliver a thunderous 130-150+ decibel blast—comparable to a real locomotive. The Extreme Quad version packs the biggest punch, followed by the Quad and Dual options.

Which version of the DeWalt Train Horn is the most powerful?

If you want the absolute loudest, go with the Extreme Series Quad Trumpets. These oversized trumpets generate the deepest and most intense sound in the DeWalt lineup.

What color options are offered for the DeWalt horn trumpets?

You can personalize your horn with trumpet finishes in:

  • Black (sleek and aggressive)
  • Red (bold and eye-catching)
  • Chrome (shiny and premium)

These finishes are available across Dual, Quad, and Extreme Series models.

Does each DeWalt Train Horn come with a remote control?

Yes! A wireless remote is included with every DeWalt horn. It’s already synced out of the box and works up to 160 feetaway. Need more range? Upgrade to our extended-range remote (up to 2000 feet).

Will I receive a battery and charger with my DeWalt horn purchase?

It depends on the package you select. We offer:

  • Horn-only kits (for those who already own DeWalt batteries)
  • Full kits that include a 20V DeWalt-compatible battery and charger

Choose your preferred setup before checkout.

Can I blast the horn immediately after unboxing?

Absolutely. Your DeWalt Train Horn arrives pre-assembled and tested. Simply slide in a charged 20V DeWalt battery and you’re ready to unleash the sound.

Is it safe to mount the DeWalt horn inside my vehicle?

We advise against mounting the horn under the hood due to heat exposure. Safer locations include:

  • Behind the grille
  • In a truck bed
  • Mounted in a protected area

Keep in mind—these horns are designed for handheld or portable use.

Should I disconnect the battery when not using the horn?

Yes. If your DeWalt Train Horn won’t be used for more than 5 hours, disconnect the battery to avoid slow drain. The receiver inside is always listening for the remote signal, which can slowly drain your battery if left connected.

Is the DeWalt Train Horn waterproof or weather-resistant?

The horn is water-resistant, not waterproof. It can handle a few sprinkles or light mist, but you should avoid heavy rain, car washes, or full submersion.

How long does a DeWalt battery last with the Train Horn?

A single fully charged DeWalt 20V battery can deliver hundreds of horn blasts. Runtime depends on the battery’s amp hour rating and how frequently you activate the horn.

Can I use this horn to scare birds or pests away?

Yes! The loud blast is excellent for deterring birds, wildlife, and even unwanted guests. Many users buy them for farms, rooftops, marina docks, and more.

Can one remote control more than one DeWalt Train Horn?

Yes! You can sync a single remote to multiple DeWalt horn units, allowing you to blast multiple horns at once for an even louder impact. All must be BossHorn models to work correctly.

Can I connect more than one remote to my DeWalt Train Horn?

Yes! You can pair multiple remotes to the same horn—whenever you want. This is perfect if you want a spare remote or want to share horn access with others. Extra remotes are sold separately and easy to sync.
