More lights! More lights! I've always concluded that "active" lights are better than "passive" reflectors. With a reflector or vest, you have to wait until the car's headlights swing into the right position to reflect. Blinkies grab more attention without relying on headlights to pick you out. On second thought, just add a few more blinkies to your helmet and backpack and then add a vest and some reflective tape on your bike. Never hurts to be seen.
