I have a PAL light and don't have that problem.If you hold the button down till you see it flash twice,it is then off(or in it's constant on feature.I do like the always on feature and it sits by my bed.In a power outage it is the easiest flashlight to find in the dark.Once while my DW was cleaning she knocked it off the night stand.I finally found it at 2A.M.when I got up to take a standard nightly walk.
