Whatever you end up doing, you'll be better off getting 2 lights for the front. One for the handlebar, and one for your helmet. This will give you redundancy for when you forget to charge the batteries as well as allowing you to illuminate your way when it turns goes up/down hills etc... Or when you realize that your lights aren't quite as bright as you thought they were going to be due to rain/snow/fog/daylight savings time ending.
