Hi Dave ,, I have a 07 Brute 750 . I actually want to do the same thing.. I have a friend in the neighboorhood , who has a old foreman 350 . he did alot of add ons to it , I know he did the hids, he installed 2 rear tailights and hooked them up so they flash alternatly ( for when he plows) and I believe he wired in a reverse light . he's hard to get in touch with because of his work schedule. I'll ask him as soon as I see him.
I thought I had seen a reverse light kit some where on the net, maybe on ebay. I think it was made by moose .
found one on ebay for cheap ,, http://cgi.ebay.com/ebaymotors/ALL-N...Q5fAccessories
I actually wouldn't mind installing a turn signal kit and flashers and horn for when I plow in the winter also. I do alot of driveways in the area and ride to all of them . I use hand signals now. Cops don't bother me when they see the plow on and I'm riding slow during a snow storm. they know i'm not out riding like a mad man causing problems on the road way.
I'll see what I can find out from the guy in the neighboorhood. when I do I'll let you know.
