Apparently, some people worry that their lighting solutions just aren't portable enough. That's the only reason I can think of for the Metro Roll-Up Lighting to exist. It's a thin strip of lights that can be rolled up into a circle, like a roll of tape or something like that.
You know what other lights roll up? Christmas lights. They roll up really easily, although I assume this solution won't get tangled up as easily. And hey, the roll-up lights are sure to be a hit at parties, with you busting out a roll of plastic only to turn it into a long, thin strip of lights. I guess. I don't know, maybe I'm just a curmudgeon, but it's hard to get excited about what are essentially giant, light-up snap bracelets.
