Keep the Japanese bomber planes from being able to see houses lit up if they're attacking Alaska or Hawaii while still allowing you to move around in the dark without tripping over stuff.

I strongly suggest that you folks either read up on the history of the United States in World War 2 or start watching the History Channel. Blackouts were not put in place just to protect Hawaii and Alaska. Within a few days of the attack on Pearl Harbor almost every American plane in Hawaii and the rest of the Pacific Ocean area had been destroyed. Every capital ship lay in ruins at Pearl Harbor. The pacific coast of the United States was completely undefended. Experimental long range nazi bombers approached within 12 miles of the east coast of the U.S. Thousands of American sailors were killed by nazi submarines sinking ships not even 5 miles off the coast. Every American city within 200 miles of each coast was under the threat of aerial attack.
The War Department ordered that all lights facing towards the coast had to be reduced or turned off. Merchant ships off the coasts were lit up by the "skyglow" from the City lights, making them easy targets for nazi submarines. It got so bad that recreational boaters were pressed into service to try to spot surfaced submarines. Pipelines had to be constructed from Texas to New York to deliver petroleum products because of the sinking of tankers off the east coast.
In New York City, almost all street lights were disconnected or had very low wattage lamps installed. The lights that remained on had their globes painted mostly black to look like that picture of the blackout bulb. The "Belt Parkway" the newly constructed highway that went around the New York City boroughs of Brooklyn and Queens, had been equipped with over 2500 GE M2 low pressure sodium luminaires. On these lights the vacuum flask was painted black except for a one inch strip on the bottom of the flask.

Fascinating information! I knew that was what the blackout lamps were for, but still...
