A farm across the road has started doing a bit of warehousing. Two or
three artics unload and load into a secure barn. No problem with this.

What IS bothering me are the reversing "beepers" on the forklift trucks.
They seem very loud - I can still hear them if I walk 1/2 mile down the
lane. This is a quiet rural area, the loudest noise is the sparrows. To
serve as a warning something much quieter would, I feel, be sufficient.

I'm on pretty good terms with the people responsible and they say it
annoys them too but the insurance company insists that they have these
beepers. I'm prepared to talk to the insurance company but to do any
research I need to know:

What is the proper term for these beepers so that I can Google?

Anybody point me in the right direction?
