Abstract: Conspicuous, informative lights make bicycling on roads safer and more comfortable, day and night. Pairs of bright, non-flashing, non-glare lights are positioned so motorists can easily detect and recognize the bicycle, then easily determine its space requirements and motion. They also light the road ahead at night. In one embodiment, thin clusters of LED's shine white ahead and amber rear, giving the bicycle a wide presence on the road. This keeps motor vehicles at a safe distance and decreases motorist impatience.
