BTW, just so I'm not misinterpreted, I use BOTH reflectors AND a rear facing red light and front facing white light while I'm riding at night. I only need blinking lights for my safety and not the 1400 lumens lights I would use on a 24 hour mountain bike race. I live in the city and the ambient light is enough to negotiate without lights, but I ride with reflectors and lights so idiots don't hit me.
