Might want to get this for my bike/gear.  Paint that is invisible by day but lights up in headlights at night.  Developed by Volvo.

At work now and can't embed the video, but here's the article.  Video is at the end.

That is some really cool stuff.
I wonder if the permanent variety is colorless after application also. It does not say specifically.

Some catches - that stuff is temporary, and only available (but for free) in two locations, in London right now.

There's commercially available reflective spray paint

the make the beast with two backsers can't see us during the day, that's the problem.

which is weird considering they have no such make the beast with two backsing problem seeing the text message on their phone... in their lap.

Reminds me of illuminite --fabric that looks normal during the day, but is highly reflective at night.  The plus side is that you don't have to reapply anything. The down side, is that most options are for bicycling and running. Not sure why it isn't found in more moto apparel...
