World War II Blackout Bulbs

1941 - During imperialist American Occupation, blackout practices  in Manila and other parts of the Philippines are held in  anticipation of the Pacific Theatre phase of World War II;  apart from the blackouts wherein lights are dimmed so as not to make a certain place conspicuous  and easy  target for attacks, the colonial United States and Filipino officials also establish evacuation  centers and "air-aid drills" some five months before the Japanese  Imperial Army begins invading the US-occupied Philippines after bombing the  United States naval base at Pearl Harbor (December 1941).
