Volvo's pitching LifePaint, a supposedly easily-washed off reflective spray paint for cyclists and other at-risk road users to cover themselves in at night.
LifePaint is a unique water based reflective safety spray. Invisible by daylight, it glows brightly in direct glare of car headlights. Making the invisible, visible. LifePaint washes off, and will not damage the colour or the surface of your chosen material, lasting more than a week of normal usage.
LifePaint can be used in all sorts of ways. Please note that it works best on textile materials. Applied to clothes, shoes, helmets, pushchairs and children's backpacks – even dog leads and collars.
It looks terrible in the promotional artwork—a chalky mess that cyclists will now be expected to wear unless they want to be held responsible for their own deaths—but this seems like just the sort of thing the street finds its own use for.
