& I have a neighbor kid that likes riding behind me when I backup..which is another can of worms
I originally decided to be frugal ($13) & got the first one in the following photo
onto the story
...the back up alarm me & my son installed last Sept died a slow death over the course of the winter
it seemed to dislike the extreme -temperatures we had here in VT this winter
the colder it got, the worse it sounded until it died
here's the old unit which was very loud, more of a treble sound

so I upgraded after returning the defective one to the parts store & paid the price difference of $24, this one is supposedly commercial, hopefully it lasts

video of the new backup alarm later
I think its an inexpensive protection policy hopefully
