I placed the lights on my bike the day they arrived. Easy to follow directions. They're very bright as advertised, and they do not take up much room. I love the fact that they easily detach. As long as I don't leave them on the bike when I leave it locked outside, no one should ever steal them.
Lights are smaller than expected but not tiny. Haven't put batteries in yet to test light for brightness, but LED lites put out good light so I'm not worried about them being too dim. These light should at least make you visible. How far the front light will shine will be the important feature, but should at least give light in the immediate foreground. Whether it's a narrow beam or wide will be important to find out. If possible, I will update this review on those aspects.
