Ah, special material, got it! Reminds me of the material Brando wore in Superman, to make them glow white.

- leoedin 13y agoThe extent to which retro-reflective material reflects light back is actually quite incredible. I got a new bike light which for weeks I thought was REALLY REALLY BRIGHT until I realised that although it was making street signs 200m away flash brightly, it was only making them flash for me. Even a few degrees out and the reflectivity dropped remarkably.
