Brightness controllable flashlights

In a flashlight, the combination comprising:

• a battery;
• a switch having an OFF position not connected to said battery, a first ON position connected to said battery, and a second ON position connected to said battery;
• a light emitter assembly;
• a controller in circuit with said battery, said switch and said light emitter assembly, said controller controlling electrical power to said light emitter assembly for producing a first light output when said switch is in said first ON position and for producing a second light output when said switch is in said second ON position;
• and
• a switch actuator coupled to said switch and translatable by a first distance placing said switch in said first ON position and translatable by a second distance placing said switch in said second ON position.

A method of indicating near exhaustion of a battery in a flashlight including a light emitter, comprising:

• regulating power from the battery to the light emitter for providing constant brightness of light output over time;
• detecting near exhaustion of the battery;
• and
• abruptly reducing power to the light emitter for providing an abrupt decrease in light output when near exhaustion of the battery is detected.

In a flashlight, the combination comprising:

• a battery;
• a light emitter assembly;
• a switch in circuit with said battery and said light emitter assembly, said switch having an OFF position, a first ON position coupling said battery to said light emitter assembly for producing a first light output, and a second ON position coupling said battery to said light emitter assembly for producing a second light output;
• and
• a switch actuator coupled to said switch and translatable by a first distance placing said switch in said first ON position and translatable by a second distance placing said switch in said second ON position.
