I've got 180 miles on the Juiced Bikes CrossCurrent X. Replacing batteries on the CCX taillight after I thought it broke. Can't blame me for thinking that, right? :-D Seems the light is more sophisticated than I thought and the steady mode stops working when the batteries get weaker... This video shows how to take off the light, open it up, and change the batteries.
