I have been using these lights to bike to work early in the morning when it is mostly dark out. I admit I was worried about purchasing this type of product online, as I just got into biking and am unfamiliar with what I needed. I did look at my states requirements, and purchased these as they met the statute. The front light is VERY powerful, and has a bright, less bright, and blink setting. I had it on the brightest setting when biking, and ended up positioning it on the center of my handlebars.
