My ebay light changer came in the mail yesterday. The shiny coin is a quarter for size comparison.
The directions said to mount it as low as possible without surrounding it by steel ( DOH!! ) so I put it on the crossbrace for my center stand.
Now that it's installed ( total time was under 5 minutes as a tie wrap holds it in place), I'll be willing to bet that the light in question will have cars there all week when I pull up.
I'll report back as soon as I find out if it works.
