Brilliant, I still remember the original "cats eyes" road studs from when I started driving, they actually worked tends times better when compared to todays reflective studs that have replaced them, driving down a road and being able to see far into the distance made driving so much nicer at night..

I would love to see these glow in dark ones, I'd bet they would be as good if not better than proper cats, for one thing you would not have to drive over them to clean them

The original ones where glass balls in a brass tube with a rubber edge, the tube would fill with water and the glass ball depressed into the tube when you drove over them cleaning them, such an elegant and simple design to be replaced by a little bit of crappy reflective plastic, so I for one can't wait to see glow in the dark roads..
