wow great hunt. cyclists meet with accidents because other drivers they trust on the road do not anticipate how fast the cyclist can go and how many rules they can break. sometimes its also because people are driving cars recklessly or they have blind drivers. while in day time, its easier to spot a cycle, at night, may be led light is better than reflective layer. but then make sure the battery is charged! because nobody had thought of a light before this, or may be they had and reflective layer were assumed to be safer. but who knows. wow hunt.
