Train Horns Compatible with Bosch Batteries

The Bosch-compatible Quad Pro is the loudest option in our lineup. Its extended metal trumpets produce the deepest and most powerful train-style sound, designed for maximum presence and wide sound coverage.

No. The color only changes the look — not the tone or volume. All models sound equally powerful when using the same trumpet size and compressor setup.

No, the battery is not included. You can use any original Bosch 18V battery, or order one from us as an optional add-on.

Absolutely! All our Bosch Train Horns work perfectly with any Bosch 18V battery — genuine or aftermarket — so you can use the ones you already have.

Yes! Most models come with a wireless remote, with a range of up to 160 ft (≈50 m).

A regular car horn is designed for everyday road use, while a Bosch-compatible impact train air horn produces a much louder and more powerful, boss level sound. It delivers a deeper tone and significantly higher sound presence than a standard car horn, making it better suited for outdoor use, events, and demonstrations rather than everyday driving.

All Bosch-compatible train horn models — Dual, Quad, and Quad Pro — are available in three premium powder-coated finishes designed to suit different setups: Black, Red, and Chrome.

Each color option offers the same sound output and performance, so you can choose the finish that best matches your style without compromising functionality.

It’s not recommended. The wireless remote receiver draws a small amount of power even when the horn isn’t in use, which can fully drain the battery over time.

If your horn drill won’t be used for more than 5 hours, unplug the battery to prevent deep discharge and extend its lifespan.

Yes. All Bosch-compatible train horn models — Dual, Quad, Penta, and Quad Pro — come fully assembled and pre-tested. Simply attach a charged Bosch 18V battery, and the unit is ready to use.

No tools, no wiring, and no additional setup required.

With a fully charged Bosch 18V battery, a Bosch-compatible train horn provides extended use across many activations on a single charge.

Actual runtime depends on battery capacity (such as 2Ah, 5Ah, or 8Ah) and how the horn is used. All Bosch-compatible models are designed for efficient power use and consistent performance during normal operation.

A Bosch-compatible train horn produces a very loud, attention-grabbing sound that may help discourage animals in certain situations. However, effectiveness can vary depending on the environment, the type of animal, and how the horn is used.

This product is not designed or marketed as a wildlife or pest control device, and results are not guaranteed. Always use the horn responsibly and in accordance with local laws.

Bosch-compatible train horns are water-resistant, not fully waterproof. They can handle light rain, splashes, and normal outdoor moisture, but should not be exposed to heavy downpours or full submersion.

For best long-term durability and consistent performance, we recommend storing the horn in a dry place when it’s not in use.
