Illuminated safety vest
 

I just stumbled upon this while seeking out information on safety vests. It's a fairly standard-looking vest, but it's also got an illuminated strip across the back that runs from a CR2032 battery. Has anyone tried out something like this?

Note that the vendor says that it's good for both "biking" AND "cycling." How could you go wrong with an endorsement like that?
