The safety mode means that once the battery level falls below the predefined level, this selects the brightest mode that guarantees 1 hour run time to get you home. Also featuring Memory Mode, the light remembers what mode you were last in before you turned it off so that you don't have to cycle through the modes again. Finally, a futuristic mode on the light which will soon be the norm on all lights is an integrated light sensor. When you select this mode it means the light will turn on and off automatically in relation to the surrounding light conditions.
