By the time war was declared, all street lights and illuminated signs in Britain were extinguished for the duration. ALL windows and doors had to be curtained so that no chink of light escaped to guide enemy aircraft. Torches and vehicle lights had to be shielded so no light escaped upwards. Traffic lights were covered so that only a small cross of color showed. The windows of trains, buses and trams were covered with a material which prevented the glass from shattering, with a small diamond left open in the center so you could (hopefully) see where you were. Most people relied on the driver to tell them which stop was coming up next! The interior lights of vehicles were disabled in the towns, and heavily dimmed in long-distance trains.

At night in Britain, during the War, all outside lights were switched off and people had to make sure that no lights could be seen from within their houses - hence people put up 'blackout curtains'. This was done to make it harder for enemy planes to find targets. The police and air raid wardens warned people if they hadn't made their houses dark, or if they flashed torches around. Even car and other vehicle lights had to be made very dim. Often people had accidents in the blackout because they couldn't see very well at night

A blackout in time of war, or apprehended war, refers to the practice of collectively minimizing external light, including upward-directed (or reflected) light. This was done in the 20th century to keep the crews of enemy aircraft from being able to navigate to their targets simply by sight. In coastal regions a shore-side blackout of city lights would also help protect ships from being seen and attacked by enemy submarines farther out to sea.
