Care Guide

BossHorn is designed for durability and ease of use, requiring no regular maintenance. However, follow these simple care tips to ensure optimal performance and longevity:

1. Avoid Overheating

• If you continuously press the trigger, the air compressor may heat up.

• Allow it to cool down between extended uses to prevent overheating.

2. Remove the Battery When Not in Use

• Always disconnect the battery when storing your BossHorn.

• This prevents accidental activation and battery drainage over time.

3. Store in a Dry, Cool Place

• Keep your BossHorn indoors or in a protected area to avoid moisture buildup.

• While it is water-resistant, excessive exposure to water can damage electronic components.

4. Use the Right Battery

• Only use same-brand or compatible aftermarket batteries for optimal power.

• Store batteries fully charged before long-term storage.

5. Keep It Clean

• If needed, wipe down the horn with a dry or slightly damp cloth to remove dust.

• Avoid using harsh chemicals or soaking in water.

Following these simple steps will keep your BossHorn ready to blast whenever you need it! 🚂🔊

The process revealed

From Drill to Train Horn

Using a brand-new Milwaukee impact driver as the foundation, we skillfully integrate a high-powered air compressor, a remote receiver module, and a custom-engineered wiring system equipped with a new trigger button and relay. Finally, we mount our distinct metal trumpets, creating a thunderous and attention-grabbing blast.

Best train horn on the market!!

My other option was high pressure air and a permanent horn under the hood of my F550 truck camper. Way too expensive. Boss Horn was a fraction of the price with much more versatility and no sacrifice of decibels. Love this horn and the reaction of everyone that hears it is priceless.

Awesome gadget!

I'm in road construction and often work with live traffic situations. The Boss Horn really got those 'speeders' attention when they sped through our work zone. VERY EFFECTIVE. The Boss Horn brings smiles to my crew mates every time. Love this product.

Great product

Works perfectly, and is even nicer than expected

Great horn

I am very pleased with the quality and performance of the horn, I have the Milwaukee with the long deep horn. Works great. I have it mounted on my airplane. Even from a 1000' up it works great.

Loud and the extended range remote is awesome

We got one of these for work around the rail road to warn contractors that a train is coming it’s a familiar noise since the real train horn they hear daily. But the extended range remote for sure we have used it 500ft away no problem . No matter how loud the job site they will hear it.

This is the “Boss” of all handheld horns

I've been testing out the Milwaukee Premium Boss Horn for a few days now. It's awesome being able to use it with the remote. It's been entertaining to see neighborhood kids running around trying to figure out where the trumpeting noise is coming from.
