    • If the flashlight flickers, works intermittently, appears dim or faded, or does not turn on, check and verify that:
      • Each battery is fully inserted matching the polarity (+/-) on the battery holder.
      • Each battery end is touching a  metal contact in the battery holder.
      • The battery holder contacts are clean and the springs are not bent sideways.
      • The flashlight's inner spring is firmly attached and not bent.
      • The battery holder is inserted into the flashlight with the positive (+) end first.
      • The tail cap is twisted on tightly.
    • Firmly press the power button on and off several times:

      • If the flashlight still does not turn on, replace the batteries.
      • If the problem persists, contact GearLight for a replacement.


    • Inspect the flashlight monthly and carefully remove any damaged batteries and clean any corrosion.  If the flashlight is used less than once a month, remove the batteries between uses.  Lubricate all threads and rubber O-rings with petroleum jelly twice yearly.
