This is easiest way to keep yourself visible on the road. These two bike lights are magnetic. Just stick them on your bike and you're ready to go. It's that simple. You'll get a white and red light for the front and back of your bike, each of which features three modes for flashing and steady light. The lights are visible from a wide angle, and if you don't have a metal bike, there's even attachments for sticking on the blinkers. When you're done with your ride, simply pull off the lights and take them with you.
