SEE ME Warning Light

It looks homemade, it runs on 8 AA batteries and it weighs about a pound (448 g). But the patented SEE ME warning light is super bright. Its LEDs flash yellow to spell out a command (plea) that might keep a roadie from being hit from behind. The Boston-based manufacturer says a University of Michigan study found that drivers pay more attention to text warnings than those that use symbols. You wear this one around your waist with SEE ME in the small of your back. There's also a non-flashing white-light mode for illumination when making roadside bike repairs or checking a map. Retail price: $119. http://www.seemecorp.com
