Huh? If someone told me I had to choose between reflectors or lights I would not hesitate but to choose lights. Lights are visible further away as well as close up, their more visible at angles. I guess if some one said that my only light choices were to use the lowest power small dim pin prick led's well then maybe you have a point. But I could get a much more adequate lighting for under $100 for both front and rear and be seen far better then any reflector system could do.

But like I said before, I chose to use both.

A under $100 dollar lighting system could compose of a Cygolite Hotshot for $35, and the Cygolite Expilion 170 for about $55. Those are the brightest lights on the market and cost less then $100 for both. Then with the $10 you have left you could get a pair of JogALite reflective leg bands or a safety vest.
