Query: Not bright at all

I've been using this light for about a year now and it is not worth the money I spent on it. It is a bike that will let cars see you, but that is pretty much it. I ride in a fairly dark area, and if I ride more than 4mph, I can't see a thing. The mount is also poorly designed and never seems tight.The only real benefits to this light are that it is cheap, and it uses AA batteries, which can be found pretty much anywhere, and the battery life is good.If you need a light that will actually help you see, look elsewhere.
