[[caption-width-right:320:'''[[TalkingWithSigns YIPE!]]''']]

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 DynamiteCandle). ThisIsGonnaSuck.

Bonus points if the revealed monsters ([[IgnoranceIsBliss or even the match-holder himself]]) blow out the match, implying that someone's going to be in a lot of pain while [[RelaxOVision conveniently preventing the viewer from actually seeing it]].

In RealLife, 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 immolate anything in range), scattered flammable chemicals such as gasoline and paint thinner giving off explosive fumes, or low-hanging easily combustible materials.

[[folder:Advertising]]
* The "Mad World" commercial for ''VideoGame/GearsOfWar'' 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 [[ByTheLightsOfTheirEyes 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.

[[folder:Comic Books]]
* Early in Jeff Smith's ''ComicBook/{{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 [[MindScrew just to mess with the poor guy]].
* One issue of Marvel's ''[[ComicBook/GIJoeARealAmericanHeroMarvel 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 ''ComicBook/DeCapeEtDeCrocs''. The heroes went to a dark room they assumed to be the exposive storage room. Eusebio lit a candle and revealed they were in the food storage room.
* One ComicBook/{{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.
[[/folder]]

[[folder:Comic Strips]]
* Creator/PhilFoglio's ''ComicStrip/WhatsNewWithPhilAndDixie'' [[http://www.airshipentertainment.com/growfcomic.php?date=20070114 comic]] in ''Magazine/{{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 ''ComicStrip/{{Garfield}}'' strip does this once, during the storyline when Garfield ran away from home.
[[/folder]]

[[folder:Films -- Animation]]
* ''WesternAnimation/FindingNemo'' actually does this with [[AlluringAnglerfish the Anglerfish's]] lure.
* ''WesternAnimation/{{Hoodwinked}}'': Wolf and Twitchy are in a mine cart and enter a tunnel. Twitchy looks for candles.
-->'''Wolf:''' Wow, those nice and bright. What kind of candles are those, anyway?\\
'''Twitchy:''' Uh, "Deena Meetay" -- must be Italian!\\
'''Wolf:''' Ah! Lose the candle!
* Used in the ''Franchise/WallaceAndGromit'' short ''WesternAnimation/AGrandDayOut''.
* In ''WesternAnimation/TheCatCameBack'', 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.
* ''WesternAnimation/TheCroods'': Grug is trapped inside a cave, so he tries to make a fire. When he finally does, it reveals a tiger behind him. The tiger blows out the torch, [[spoiler:but stokes it back when it gets spooked by an offscreen explosion.]]
[[/folder]]

[[folder:Films -- Live-Action]]
* Dramatic usage: One of the characters in the movie ''Film/PitchBlack'' 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.
* ''Film/{{Cloverfield}}'' does this by utilizing a camcorder's night vision in an abandoned subway tunnel.
* In the 1999 film ''Film/{{The Mummy|Trilogy}}'', as Rick (Creator/BrendanFraser) and Evy (RachelWeisz) 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 ''Film/{{Juon}}'' 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, ''Film/TheGrudge''. (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 ''Film/ScaryMovie 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 ''Film/TheDescent'', 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'''.
* A variation is used in ''Film/TheRocketeer'' in which [[TheDragon 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 ''Film/ShaunOfTheDead'' 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 ''Film/{{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 ''Film/{{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.
* ''[[Film/PoliceAcademy Police Academy: Mission to Moscow]]''. The first thing Harris sees when lighting a match is a "no fire" sign. The next thing we see is an explosion.
* In ''Film/MrHulotsHoliday'', the eponymous vacationer lights a match inside a shed which is revealed to be filled with fireworks.

* ''Discworld/MonstrousRegiment'': 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: [[spoiler:the zombies aren't after them, and they'd probably be safer down in the catacombs than in actual combat.]]
* ''ThePhantomOfTheOpera'': Raoul and the Persian escape from the Phantom's DeathTrap 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.
* In sequel to ''Literature/TheThreeMusketeers'', ''Twenty Years After'', their servants discover the ship they're on is packed with explosives, about to go off, this way. They were appropriately terrified.

[[folder:Live-Action TV]]
* ''Series/TheAndyGriffithShow'' once has Barney, while looking for a lost goat, enter an dark shack. The highway department is using dynamite to build a new road near Mayberry. Fortunately when Barney lit the match he doesn't light anything else.
* Subverted in the ''Series/DoctorWho'' episode [[Recap/DoctorWhoS29E4DaleksInManhattan "Daleks in Manhattan"]], when the ColdOpen involves a man being lured into the prop room backstage at a Broadway theater by suspicious sounds. He lights a match, which reveals a face leering at him, belonging to a dummy of a pirate. He breathes a sigh of relief, puts out the match, and then is ambushed by a PigMan.
* A rare live-action example occurs in the final episode of the first season of ''Series/FoylesWar''. 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, revealling that they are surrounded by barrels, having sought shelter in the airfield's fuel dump. Naturally, Foyle recommends that his son put the lighter out.
* It happens in an episode of ''Series/TheIncredibleHulk''. 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.

[[folder:New Media]]
* Once read on a mine exploration forum:
-->If you can light a cig it's fine.\\
If you struggle to light a cig it's poor.\\
If you can't keep a cig lit it's bad.\\
If you can light a cig AND everyone else around you, along with [[http://en.wikipedia.org/wiki/Firedamp the entire mine]], then it is bad too.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'': The illustration for the "Corpse Candle" spell in the ''Spell Compendium'' is exactly this trope. The wizard using it finds himself entirely surrounded by spectral undead, along with the caption:

[[/folder]]

[[folder:Video Games]]
* ''VideoGame/MonkeyIsland2LeChucksRevenge'' features the "room full of explosives" variation.

When the subject of sea monsters is brought up, Chepito turns his head to reveal that they're already surrounded by them. But it's okay, because the light is what keeps them at bay.
* The opening sequence of ''VideoGame/{{Silent Hill|1}}'' and its film adaptation. Both protagonists go into a dark alleyway and light a match to find that they are surrounded by bloody corpses, chain-link fences, and gray demon children.
* In the final act of ''VideoGame/PoliceQuest: Open Season'', you enter a dark room in the theater, and turn on your flashlight to reveal the BigBad, who knocks you out and [[NoGearLevel strips you of your possessions]].
* An unscripted, but likely, example from ''VideoGame/TheElderScrollsVSkyrim'': A later mission has you faced with a field of vision-obscuring fog, naturally calling for the use of the Clear Skies ability, revealing [[spoiler: [[BigBad Alduin, The World Eater]] [[JumpScare about a meter and a half in front of your face]]]].
[[/folder]]

[[folder:Web Animation]]
* The Flash cartoon series ''Lenny Loosejocks'' has an episode where the title character goes spelunking, carrying a flashlight. At one point Lenny falls through a hole, and turns on the flashlight to survey the surroundings, revealing a huge orange snarling monster in front of him. He quickly turns off the light again, then turns it on again... and the monster is gone. [[OverlyLongGag Rinse and repeat]] for a minute or so before Lenny shrugs his shoulders and moves on.

[[folder:Web Comics]]
* ''Webcomic/GirlGenius'': The protagonists find out this way that [[http://www.girlgeniusonline.com/comic.php?date=20060512 they are in an ossuary...]] and the "rock" with dry moss they alighted is in fact a skull.

[[/folder]]

[[folder:Web Video]]
* In {{WebVideo/Idiotsitter}}, Billie is led into the darkened garage by Joy, who explains the situation of "Fight Day" by matchlight. Then the match goes out and Joy flees, leaving Billie to light a match of her own-revealing Gene right behind her, who lampshades this trope.
-->'''Gene:''' I'm behind you, and that's scary!

[[folder:Western Animation]]
* Plenty of ''WesternAnimation/LooneyTunes'' cartoons. Often combined with the obligatory ByTheLightsOfTheirEyes.
** Wile E. Coyote in particular has a bad habit of finding shacks full of explosives.
** Yosemite Sam also inadvertently ends up in powder houses every so often, especially when in pursuit of WesternAnimation/BugsBunny.
* Used in almost every episode of ''WesternAnimation/ScoobyDoo''.
* Done by Plucky at the end of the ''WesternAnimation/TinyToonAdventures'' renditon of "[[TheyMightBeGiants Particle Man]]".
* On ''WesternAnimation/ThePerilsOfPenelopePitstop'', episode "Arabian Desert Danger", after the Ant Hill Mob were tricked into driving into an oil pipeline, Dum Dum struck a match inside the sealed pipeline. Of course, this led to a [[NonFatalExplosions Non-Fatal Explosion]].
* A variation occurs in ''WesternAnimation/TheSimpsons''. Homer ends up in a dark closet, and lights a match...
-->'''Homer:''' (''sees skeleton'') Aah! (''drops match, light goes out'') That was a close one... (''lights another match, sees skeleton again'') Aah! (''drops match again'') That was a closer one! (''lights yet another match'') Aah! (''drops match yet again'') Oh, thank God I'm out of matches! Oh, no, here's another one...
* Spoofed in ''WesternAnimation/{{Futurama}}''. Leela and Fry are trying to find their way out of a pitch black area. Fry lights a match to see better and promptly screams, causing Leela to cry out "What? What is it?" Fry responds, "I burnt my finger."
* A variation occurs in ''WesternAnimation/AvatarTheLastAirbender''. In the episode "The Waterbending Scroll", Aang is seperated from Sokka by a huge cloud of smoke originating from smoke bombs used in a battle between pirates and firebenders. Aang, getting tired of the smoke, blows it away, hoping it allows Sokka to find him... only to find himself in the middle of a battle with no less than 7 weapons pointed at him. He promptly brings the smoke back.
* In one episode of ''WesternAnimation/Ben10AlienForce'', season 3, the PowerTrio are exploring a mine. Kevin finds a big pile of boxes, and lights a flare so he can read what's written on the boxes. "TNT" is written on the boxes. Ben quickly blows out the flare. Kevin yells "Hey!" and... [[TooDumbToLive lights another flare.]] Luckily, Ben blows that one out, too, and Gwen berates Kevin for his stupidity.
* ''WesternAnimation/JonnyQuest'' episode "The Fraudulent Volcano". When Jonny and Hadji sneak into the enemy base and end up in the dark:
-->'''Hadji:''' I wonder what's in those boxes?\\
'''Jonny:''' Wait a minute, I got a match. (''lights it'') It says E...X...P...L...O...Ex...Explosives!\\
'''Hadji:''' Forget I asked you! Let's get out of here!
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Not a match in episode [[Recap/MyLittlePonyFriendshipIsMagicS1E6BoastBusters "Boast Busters"]], but otherwise played very straight: While they are in the cave of the Ursa Major, Snips complains about the darkness and Snails uses magic to create a light at the tip of his unicorn horn. And thus the two foals discover that they are just under the nose of the giant ursine monster.
* ''WesternAnimation/DangerMouse'': In "The Strange Case of the Ghost Bus", DM and Penfold traverse a dark tunnel, and the two cannot fathom why they're holding each other's hand or why they feel like fur gloves. DM strikes a match to show they've both been holding hands with a yeti.

[[folder:RealLife]]
* 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.
