You want to be seen at night? Go here :
http://www.streetglo.net/streetglo_files/helmet.decals.htmI've got a super reflective kit on my helmet and have nothing but good things to say about it. I have a super reflective decal on the back of my helmet and it definitely keeps the cagers further off of my tail at night. I commute to work at night, so this kind of stuff is pretty important to me. :)
