"Put That Light Out!" is the seventh episode of the fourth series of the British comedy series Dad's Army. It was originally transmitted on Friday 6 November 1970. Synopsis The Walmington-on-Sea Home Guard are sent to guard the local lighthouse − and Corporal Jones is in charge. Plot Mainwaring recently sent a letter to GHQ requesting the platoon's use of the local lighthouse as a guard house, and has just received permission to do so. Jones' section are the first to test this new guard house and prepare to move off that same evening. Walker is unable to attend because he is delivering some essential supplies, but the Lewis gun has been fixed, no questions asked. They arrive at the lighthouse and set themselves up. They have been asked to stand guard from 8:00 in the evening to 2:00 in the morning, much to Godfrey's disappointment. He is suddenly taken short and has to go downstairs, as the nearest convenience is right at the bottom. Jones asks Frazer to check on Godfrey, but he refuses. He tells the story of his school friend Wally Reagan... He had been asked to watch over a lighthouse and, one night, he heard a slithering and a moaning from downstairs. He had gone downstairs to investigate, but had been scared back up because the slithery thing was following him up the stairs. He locked the door, but the slithery thing was trying to get in... Suddenly they hear a knocking on the door and scream, but it is only Godfrey. They try the telephone, but they've been cut off. Frazer panics, and Pike reckons it's the slithery thing coming to get them. Jones takes control, and pulls a switch. Suddenly, they hear a large moaning sound, and they realise they've turned the main lamp on, lighting up the whole town. They attempt to turn it off, hoping there isn't an air raid that evening - just as the air raid siren blares. They try to block out the light by holding a blanket up in front of it, but the heat from the lamp sets it on fire, forcing Pike to put it out with a fire extinguisher, coating Jones' trousers with foam in the process. It is Wilson and a panicking Warden Hodges who discover the light, and inform Mainwaring and Mr Alberts, another ARP Warden, respectively. They discuss how to put it
