A trope commonly found in animation; two or more characters, usually hiding from something, have found themselves in an entirely pitch-black environment. One of them remarks on or complains about how dark it is. The other strikes a match — but the sudden burst of light reveals that the characters are, in fact, standing in the middle of an amazingly dangerous environment, be it a room filled with monsters (who have, up until this point, been remarkably quiet) or — to give the danger an added boost of irony — a room packed with an unimaginably large store of explosives (especially if the "match" turns out to be a Dynamite Candle). Guess what happens next?
Bonus points if the revealed monsters (or even the match-holder himself) blow out the match, implying that someone's going to be in a lot of pain while conveniently preventing the viewer from actually seeing it.
Subtrope of Lightswitch Surprise, which covers any surprising sight when a light is turned on.
In Real Life, this is why matches and lighters are strongly advised against as immediate emergency lighting, especially after a disaster such as an earthquake or tornado where there could be burst gas lines (which won't even give you the warning of a labeled dynamite box before they explode and incinerate anything in range), scattered flammable chemicals such as gasoline and paint thinner giving off explosive fumes, or low-hanging easily combustible materials.
- The "Mad World" commercial for Gears of War uses this trope for excellent dramatic effect. Being pursued by alien forces, Marcus Fenix dives into a darkened building by crashing through a window. Although it is almost pitch-black inside, he spots countless spots of light, and opens fire upon them. The bright muzzle flash of his machinegun reveals that these eyes belong to a gargantuan, lobster-like creature that fills the entire room.
- Early in Jeff Smith's Bone, the Red Dragon asks Fone Bone for a light for his cigarette in pitch-darkness, giving Fone his first brief, terrifying glimpse of a dragon. Eventually you might realize that, since the Red Dragon can breathe fire, he might have done this just to mess with the poor guy.
- One issue of Marvel's G.I. Joe has a group of Joes chasing a Cobra vehicle. They later reach a point far from their starting point and one fires a flame to see where they are. He reveals the Cobra forces that are about to ambush them.
- Subverted in De cape et de crocs. The heroes go to a dark room they assume to be the ship's magazine. To everyone's horror, Eusebio lights a candle, revealing they're in the ship's larder. A later scene plays it straight via inversion (they thought they were in the larder, it turned out to be the magazine).
- One Venom storyline culminated with him chasing a criminal gang into a warehouse filled with highly explosive drug components, then cutting the power and waiting for them to light a match.
- Phil Foglio's What's New? with Phil and Dixie comic in Dragon magazine #50 uses this. Phil and Dixie are exploring the TSR dungeon in the dark and realize there is someone else with them. Phil lights a match, revealing that the other creature is actually a demon. Then the demon blows out the match...
- A Garfield strip does this once, during the storyline when Garfield ran away from home.
- Finding Nemo actually does this with the Anglerfish's lure.
- Hoodwinked!: Wolf and Twitchy are in a mine cart and enter a tunnel. Twitchy looks for candles.

- Used in the Wallace & Gromit short A Grand Day Out, with the robot inside the rocket's fuel tank.
- In The Cat Came Back, after falling down a mine shaft and seeing a pair of eyes, the main character lights a match only to find himself surrounded by rats, bats and snakes. The first rat then helpfully blows out the match.

- Lucky Luke: Go West! features villains Crook and Bartleby, after a By the Lights of Their Eyes moment in an abandoned mine, lighting a match only to find themselves next to a mountain of dynamite boxes. However, the match isn't the biggest problem... more pressing is the fact that Rantanplan was chasing after them with a lit stick of dynamite, which he lets go at their feet.
- Space Jam: Bugs Bunny and Daffy Duck are digging their way to Michael Jordan's home to get his lucky shorts. Daffy decides to take a shortcut and surfaces inside a doghouse. He lights a match and finds himself facing Michael's bulldog, then lets out a feeble "Mother".
- In Looney Tunes: Back in Action, Yosemite Sam is vanquished when the heroes knock him into the gunpowder room of his own casino and he performs this trope.
- Dramatic usage: One of the characters in the movie Pitch Black is being stalked by monsters that fear light. His light source is running out, and he knows he's about to die. He swigs some alcohol, holds up his guttering torch, and blows a column of flame that reveals the army of monsters surrounding him. The second the flame's gone, they attack.
- Cloverfield does this by utilizing a camcorder's night vision in an abandoned subway tunnel.
- In the 1999 film The Mummy, as Rick (Brendan Fraser) and Evy (Rachel Weisz) escape the rapidly collapsing pyramid, they are forced to leave Rick's traitorous friend Beni behind, and the pyramid seals itself behind them. Beni retreats back into a massive room filled with treasure, with the only light source being his illuminated torch. Thousands of (flesh-consuming) scarabs stream into the room around him, and the light slowly goes out on the torch as they get closer, and... you know the rest.
- In the first Ju-on film (the original video version, not the theatrical version), Yuki decides to investigate the strange noises she hears coming from the attic of the house. As it is extremely dark up there, she starts to dig out her lighter. Suddenly, the camera switches to the POV of what is in the attic, which crawls towards Yuki at an incredible speed before stopping right in front of her face. The terrified Yuki slowly and shakily manages to flick on her lighter and... BAM. The ghost of Kayako is staring her right in the face, and she is not happy.
- A similar scene was also featured in the US remake, The Grudge. (In fact, the entire above scene was recreated almost shot-for-shot for the remake, but it ended up as a deleted/alternate scene on the DVD.)
- Parodied in Scary Movie 4: When Cindy moves the lighter near the ghost's face, we pan down to see the lighter is burning the ghost's hand.
- In The Descent, one of the girls is using the night vision on the camcorder to see her way through the caves. During a particularly tense scene in which several of the girls are panicking, the camcorder rests on Beth... and the sudden appearance of one of the Crawlers standing right behind her. For bonus points, this is the first clear look at a Crawler. And it's one of the most terrifying moments in the film.
- A variation is used in The Rocketeer in which Lothar uses a match to verify the identity of his sleeping victim, and the light gives the audience the first good look at him.
- In Shaun of the Dead upon arriving at the pub Shaun goes to the back room to fix the fuses and get power to the TV. When he flicks one of the switches it turns on the light outside the door next to him, illuminating a pack of zombies just outside. He rapidly turns it back off and goes back to the main room.
- Much crappier example, but also utilized in P2. While going through the parking garage, the protagonist trips and drops her cell phone. As she picks it up, the light from the screen illuminates her stalker and now kidnapper, who proceeds to knock her out and drag her away.
- Used VERY effectively in the indie film The Passage. The protagonist finds himself in a series of tunnels in the Atlas Mountains, using only candles for light. When they run out, he has to use the flash of his digital camera. It's a tense scene as he waits for the flash to recharge. The first few moments are suspenseful, and then, well, he's not alone.
- Happens in Airheads when station accountant Doug Beech is hiding in the janitor's closet. He accidentally spills some liquid on himself, and he lights his cigarette lighter to see what it is. When he sees it has a "Caution: flammable" sticker on its container, he panics.

Maisie then looks at her own reflection on a window ... only to realize that something is behind it. As it turns out, the Indoraptor had been staring Maisie in the face the entire time, less than three feet away.
- Double subverted in The Conjuring. It's only a few seconds after Carolyn lights the match that she, and we, hear "hey, wanna play hide and clap?" <clap clap>
- In Scream 3, Ghostface cuts the power to the mansion that the characters are in, causing them to flee outside, then sends a fax to the house to lure them back inside. Tom takes the bait, and lights his lighter to read the fax... only to realize too late the contents of the fax.
- In Lockjaw: Rise of the Kulev Serpent, Clayton is killed while having sex with Ashley. Ashley initially thinks Clay has come prematurely and, when the serpent pulls him off her, she lights to lighter to have a cigarette.

- In 20 Years After, the heroes' servants discover the ship they're on is packed with explosives, about to go off, this way. They are appropriately terrified.
- Dwarves had a special job to clear out pockets of flammable gas, where a miner called a knockerman would don many layers of protective clothing, a slingshot, a lamp, a ball of oil-soaked rags, and a cage of crickets, then head alone into the mine. When the crickets stopped chirping, the knockerman would back up, light the ball of rags and throw it forwards, either becoming a hero or dying as one. Due to the inherent nature of the sacrifice demanded, dwarf kings are usually taken from the knockermen's ranks, which is why there is considerable friction when an Ankh-Morpork dwarf discovers that putting a metal mesh on the lamp causes the lamp to burn blue in the presence of minedamp without setting the rest on fire.
- Monstrous Regiment: The soldiers are exploring the catacombs of the keep, and Wazzer hears noises in the dark. Someone lights a match. They are surrounded by zombies. Subverted, though: the zombies aren't after them, and they'd probably be safer down in the catacombs than in actual combat.
- The Phantom of the Opera: Raoul and the Persian escape from the Phantom's Death Trap and find themselves in a pitch black cellar full of barrels. The Persian lights his lantern so they can open up a barrel and examine the contents... which turn out to be gunpowder. The Persian quickly throws his lantern away.

- A rare live-action example occurs in the final episode of the first season of Foyle's War. During a German air raid on a British airfield, Foyle and his fighter-pilot son run to the nearest dugout that looks like shelter. In the darkness, Foyle's son flicks on his lighter, revealing that they are surrounded by barrels, having unwittingly sought shelter in the airfield's fuel dump. Naturally, Foyle recommends that his son put the lighter out.
- It happens in an episode of The Incredible Hulk. Banner and two friends are locked in a dark bank vault. Banner transforms, but no-one can see it. They hear the Hulk's breathing and realize that they're locked in with something. Cue one of them lighting a match and revealing the Hulk's face.

- Once read on a mine exploration forum:

If you can't keep a cig lit it's bad.
If you can light a cig AND everyone else around you, along with the entire mine, then it is bad too.

Iago: Like it's full of barrels of LAMP OIL!!
- This trope is why battery-operated flashlights are one of THE emergency kit tools you absolutely must have (and having one on you usable at all times is also a good idea, even if it's just a keychain light). Matches, lighters, candles, hurricane lamps and flame-based/fuel-fed lanterns ARE valid sources of light and heat in an emergency, but they are only to be used in an area confirmed to be free of gas leaks, explosive petrochemical or chemical fumes or liquids, explosives, ammunition, or quickly combustible objects. In the immediate aftermath of a major, destructive disaster (especially one such as a hurricane, earthquake, or tornado that destroys buildings and scatters their contents about), battery-powered lighting is the safest immediate lighting, because a flashlight won't ignite leaking gas — whereas a lit match will.
- This trope is also why, after a disaster, you should not, as tempting as it might be to the nicotine-addicted among people, light a cigarette until you are absolutely sure you are in an area free of leaking gas or chemicals.
