## Features

- The World's loudest cycle horn. 140dB at source the dB140 puts you in control of your safety because it gives you a way to make people know you’re there even when they aren’t looking.
- Two horn modes. “piercing mode” is a high-pitched 140db duo tone, primarily for road use, designed to be heard by car, van and truck drivers as well as pedestrians with headphones. “horn mode” is a 121dB car horn style sound designed to be used to warn pedestrians in parks and on trails.
- Two handlebar mounts included. to ensure a perfect fit with all handlebar sizes two mounts are included-one mount for bars with a diameter of 22-26mm with 4 differently sized spacers and a second dedicated to 31.8mm diameter bars (road bikes).
- Enjoy the ride. the dB140 gives you the ability to let other road users know you’re coming and that alone makes cycling much less stressful. No more shouting, fewer emergency stops, and more time spent enjoying the ride.
- The small, sleek, and completely weatherproof horn weighs only 3.6 ounces (including mount, trigger, and batteries). 2 x AAA batteries included which last up to 12 months with normal use (normal use is 6 x 1 second blasts per day).

## Questions & Answers

**Q: I'm buying this for a friend of mine who lives in NYC.  I'm worried it will be stolen off his bike though... is this easily removed and stolen?**
A: Yes, you have to remove it a half turn to pull it off to install batteries unplug the button rotated, 180° and stick it in your pocket unless that person gets mugged it won’t get stolen

**Q: Is it possible to get a longer cord? I want to mount it on my seat post facing backwards so I can alert cars coming up behind me.**
A: No idea why Maurice Pinder would take the time to provide you with false information.

“DB140 EXTRA LONG TRIGGER 150CM (5FT)” Hornit most certainly makes a longer trigger. You can easily purchase the item.

**Q: Is it easy to replace the batteries while the horn is mounted or does the horn need to be removed to get to battery compartment ?**
A: Yes it is easy to replace the batteries.  To change the batteries, unplug the thumb button wire, then turn the horn body 90 degrees (quick release) and lift off the handlebar bracket. Replace batteries, then reverse the above procedure. Re-Plug the thumb button wire. The horn works very well and load enough for people to hear you coming.

**Q: Unit works fine, but it sounds like there's a loose piece of plastic inside that rattles around when I shake the unit?  Is that normal?**
A: No! It should not sound like a rattle. If you are very concerned ask if you can return it for a replacement. 
Even if you are passed the return deadline, a reasonable company will allow for a replacement.
