I thought I had a million dollar idea this weekend.. Wireless Helmet mounted third brake light.. Then I looked it up. There are a few variations online I saw and it was patented in 1991. Oh well.
So does anyone have any experience with one of these units?
A friend has one on his helmet. All I'll say is "it works". He is a techy guy and has to have all the electronic junk. IE XM radio, GPS, Cell Phone and such..
