I made several night mountain biking equipped with several lights (2 Sigma multi-LED, a light bulb to see further and quite powerful headlamp on the helmet). This allowed me just to decipher the route 5 meters from my wheel. With this new insight, one is enough, and allows me to see clearly at 20 m (I still keep the frontal lamp that allows me to explore the sides)! It really has nothing to do, it has almost the power of a motorcycle lighting. It's almost too much, one does not really feel like driving at night. Moreover, even small power, I see better than my previous paraphernalia. Info way: the battery is very easy to attach to the gallows in his little pocket with Velcro her.
A really super affordable product. Do not hesitate!
