New LED and battery technology is light years ahead of the old stuff. These new lights are WAY brighter, more powerful and longer lasting. Lights are a necessity no matter when you ride. Most of us only think of lights for blazing a fun trail & road at night or for cummuting when it gets dark early, but they are a MUST for day time riding too. If you ride on the road you really to invest in some new light technology to make sure you are always "SEEN" and so that you can always "SEE" everything to be safe. You deserve it. Be safe & have fun.
