Your battery is dead and needs recharging. When you see your tip flash ten times fast after an attempted puff - your battery has been fully discharged.
However, this should not be confused with another similar circumstance - "The eight second cut-off" - which occurs when your have tried to drag on your LeCig for more than eight seconds. After eight seconds, your LeCig battery will flash five times, and a moment or two must be waited before you can drag on it again.
