Theres a red flashing light above the switch that turns yellow while charging and switches to green when fully charged

I recently reviewed the bicyclestore tail light and talked about the reason why you should attach lights to your bike while on the road

A small battery powered headlight will alert others to your presence and okay for riding under street lights but they arent much use on a dark road or path

But there can sometimes be an issue in the bicycle light race and that is that more is not always better
