Loud Horn

Came across the following bicycle horn, claims 140 db off 2 AAA batteries. I'd prefer one to be wired into our 12v system. Perhaps an electrical wizard could figure out a workaround.

Looks like a great alternative to hardwiring an aftermarket, larger horn.

2 AAA batteries run 3v, to hook it up to a 12v system buy 4 and wire them in series, point one in each direction.

A good loud 12 volt horn pulls about 4 amps. That's around 50 watts. You're not getting anywhere near that out of AAA batteries. 140dB sounds like a false claim.

i read several reviews. None of them actually tested the decibels. All of them said it was LOUD. Most said the downsides are it isn't a real horn sound so it doesn't register as such and it is directional.

After reading reviews, I think I would rather have a real (aftermarket) horn for a motorcycle. The Hornit is a great for a bicycle IMO.

Now this is a loud horn, but where to mount it.

You will need a trailer for the horn.
