During the Second World War, Lt. Ogleby is the troop officer in charge of a number of soldiers assigned to a searchlight and gunnery unit, somewhere in England. Ogleby visits only occasionally to check up on the unit, and in his absence Lance Corporal Tomlinson is in charge, but he struggles to maintain some kind of order over the other men, and he frequently turns a blind eye to their lack of discipline and even their local thieving. Camp comic Syd McGaffey tries to keep up with the romantic antics of his younger brother Eric who comes back from a short leave and announces that he has got married, but then soon takes up with a local girl and gets her pregnant, falling foul of her father. Ted Green is a widower with a son serving overseas and he eagerly maintains a correspondence with him. Leslie Smith is lovesick and unhappy over a misunderstanding with his girlfriend and eventually goes AWOL to get to see her. Roland Kenyon is the unit's cook and a father of six children, and he has ambitions to get a posting to a catering unit.
Light Up the Sky! was based on the play, Touch It Light which premiered in 1957. Producer and director Lewis Gilbert liked it and arranged for it to be filmed. "There have been countless films featuring heroic officers and I feel it is time the ordinary private is given his due," said Gilbert. Light Up the Sky! was Tommy Steele's first dramatic role. Lionel Bart who wrote songs for Steele's first three films, wrote a song for this film called, "Touch It Light" which Steele performs with Hill. Criterion Film Productions provided £22,500 of the budget and Tommy Steele deferred £7,500 of his fee.

Critical reception
The Guardian called Light Up the Sky! "small, sensible and somehow touching film with a whiff of authenticity about it". The Radio Times dismissed it as a "hackneyed theatrical hand-me-down". Eleanor Mannikka at Allmovie called it an "unexceptional comedy". TV Guide called it "pointless", but noted that "Comedian Hill exhibits the form that would later make him a popular television star in both the UK and US" and admitted to finding the film "occasionally amusing". Film Threat called it "A great little wartime drama" and asked "Why isn't this gem better known?" Film reviewerPeter Burnett noted that "for British nostalgia fans and cineastes in general, it will be a fabulous treat".
