I bought this light, because my old bicycle dynamo was stolen. The light serves its purpose. Weak but that no batteries are supplied for the big lamp. Why not 5 stars. In the bright red taillight already are doing that. The question remains open only as long is the battery life and most importantly how long will the holder of the big lamp. One has in the city's lights always take down, otherwise they will be stolen ... until now (to use after 3 weeks) but it looks good too.
