If you read any reviews on here saying that these lights are not that bright then it just may be that, like mine, they came with batteries that were not 100%. One of mine failed so I checked the voltage. Having found that one battery was low I replaced it and hey presto what a difference. These lights are only small but with fully charged batteries they are extremely bright. Having said that, they are small and although they would hurt your eyes to stare straight in to them the front light is not one that will light your way. I would not hesitate to buy them again and here are my two reasons why. They are the easiest lights to fit to a bike that I have ever come across having an extremely stretchy rubber that will fit around any size of tube. Because they are so easy to put on they are even easier to take off which means that when you park up your bike you can have them both unattached and in your pocket in under 10 seconds. Yes they both fit in to one normal size pocket as each one is probably the size of your little finger.
