How $7.50 could save your life.

Or at least save your face. It's amazing how many people I see on bicycle riding around at night with not a single light. As a cyclist who's also a driver, I realize how difficult it can be to see people cycling at night. I won't even get into the topic of not wearing a helmet here, but if you're going to ride at night, please invest in one of these and one of these. For a grand total of $7.50, they do a great job of making you visible to other drivers who are already distracted by cell phones, blaring music, GPS screens, pets in the car, etc. Maybe get a few for your cycling friends while you're at it, too.
