I purchased these lights to be seen and not to see with. Which would explain the cheap price. Cheap is definitley the wrong word to use for this product. The lights were brighter than expected and had the option to flash. Easily attach to handle bars and seat. Since they are rubber straps I do recommend taking them off the bike when not in use. Like anything prolonged exposure to the sun will cause them to become brittle and break. They are chep enough to replace but this way you can get a longer life out of them.
For the price I paid for these bicycle lights, it wasn't a bad purchase. Both lights were brighter than I had expected and worked really well to light the road and warn cars around me of my presence. This Bell light set really "outshines" the competition through being brighter, cheaper, and more durable than the rest.
