Review on Blackburn Click USB Front Rear Bike Set Light by Danny Poulin

I bought two sets of these bikes to mount on my kids bikes to and from school. The bulbs themselves are good and easy to install, but turning the headlights on and off is difficult for children's fingers as it takes a lot of force to press the lens to make them turn on and off. I'm sure part of the reason for the difficulty is the fact that they are very water resistant, but a simpler switch would have been better.
