I ride at night a lot now. It is dark when I go to work, and if I study at school, dark when I return home. I have about fifteen reflective pieces of tape on my bike, and four on my helmet. I have two flashing red lights on the back of my bike. One is a big light with two 'on' buttons for control of two sets of lights with varying patterns. It can be seen from the sides, and is about an inch and threee quarters in diameter in the side view. The other red light is a varying pattern flashing light that also has some limited side illumination. On my front I have a 5 LED white light on my handlebars, which is only good for being seen. On my helmet I have an old 5 volt halogen mushers headlamp. It puts out a strong white light. I figure that overdoing it a little on the lights (if that can be done), sends a message to the car drivers. One; we are here, two we are really here, pay attention. My attitude is not agressive, just that through communication is important
