Flashlights having selectively controllable brightness levels, a preferred embodiment of which comprises in combination: a battery; a light emitter assembly; a switch in circuit with the battery and the light emitter assembly, the switch having a first OFF position and a second OFF position, the first ON position coupling the battery to the light emitter assembly for producing a first light output, and a second ON position coupling the battery to the light emitter assembly for producing a second light output; and a switch actuator adapted to be coupled to the switch alternatively in its first OFF position and its second OFF position, the switch actuator when coupled in its first OFF position is translatable by a first distance placing the switch in its first ON position and translatable by a second distance placing the switch in its second ON position, the switch actuator when coupled in its second OFF position is translatable by a third distance placing the switch in its first ON position. The switch actuator preferably comprises a click-ON/click-OFF pushbutton switch actuator, for alternatively placing the switch momentarily in its first and second ON positions and constantly in its second ON position from its first OFF position; and for alternatively placing the switch momentarily and constantly in its first ON position from its second OFF position.
