This is interesting and overlaps into BMX for sure. Volvo have created a temporary reflective paint which is invisible by day but illuminates you/your bike at night when car headlights hit you. Like cats eyes in a can!

It can be applied to bikes, clothing, backpacks etc. It’s only available in a handful of shops in and around London, however Volvo intend to roll it out internationally if it’s popular. Could be fun when filming at night! Would you run it?
