During World War 2, "Blackouts" were enforced in some European countries, most famously the United Kingdom.
A blackout is basically a curfew to have all lights in the country turned off. This was a temporary law until the end of World War 2.
Having a light on or even lighting a fire outside would result in police officers turning up at your door to extinguish the light and warn or arrest you.
The blackout was designed to confuse German bombers at night. Without lights on the ground, the bombers couldn't map their location and often got lost, sometimes running out of fuel and crashing in the ocean.
The blackout saved many British cities millions worth of damage and saved thousands of lives.

You needed a ''Blackout'' because, if everyone had their lights on during a bombing raid then it would be easy for the bombers to spot you!
Orders were given for blackouts from the outset of the war in Sep 1939, in fear of German bombing raids.
