Mr. Proudfoot Shows a Light is a 1941 British World War II public information/propaganda short film, directed by Herbert Mason and produced by Edward Black for 20th Century Fox.

[3] Mr. Proudfoot Shows a Light was commissioned by the Ministry of Information and was designed to emphasise, in a humorous manner, the need for absolute adherence to wartime blackout regulations.

Proudfoot (Sydney Howard ) is an attention-seeking bore who subjects his long-suffering wife (Muriel George) and exasperated acquaintances to endless tall tales about narrow escapes from bombs.

Having unloaded a bomb over Mr. Proudfoot's district, and even hitting his house with calamitous results, the Luftwaffe bomber is shot down by RAF Hawker Hurricane fighters.

Under interrogation, one of the German crew states that they were guided to their target by a light blazing from a property that allowed them to plot out an attack.
