If you wish to use your device for a certain period, please adjust your light intensity to ensure it will last as long as your pedal power! 

Note: 

• Road conditions and scenery complexity ( ie a desert as opposed to a forest) can also affect battery runtime. 
• Colder temperature affects battery runtime.
• Depending on the age of the unit, battery deterioration can be expected over time.
