Ok
Tell me if you think this is a dumb idea.
I was thinking, if you paint a series of strips on the front tire with a spray paint, the tread part not side walls.(of course covering wheel and body etc) I know the paint would wear off quickly on the top of the tread but the low parts would stay. From the front you would see a kind of flashing effect as the tire rotated.
During the day it would give you that extra visibility.
If you used reflective paint it would probably show up at night.
It was just a thought i may give it a go and tell you if i feel i'm more visible. I will know that because people will look at me and think what the f#$@#! has that guy done to his front tire!
But they will see me

Cheers John.
