Ever since they were invented, neon lights (or their more modern equivalents) have been associated with big cities. As such, an abundance of them is often used to characterise a place or help set a mood.
Bright, colourful lights and signs may serve to establish the city as one of the following (often with a good deal of overlap):
- Crowded, chaotic, and bewildering: Neon cities are generally full of people and noise, and a visiting Country Mouse may find them confusing, overwhelming, and possibly even dangerous. A street full of signs in every language under the sun may indicate that the city is a crossroads of the world, or a melting pot of cultures.
- Hyper-capitalist: A riot of competing signs can be used to establish that commercialism and consumerism are dominant forces in society. No matter where you look, you can't escape ads trying to sell you something, and the skyline is crowded with giant Mega-Corp logos. Despite the plentiful colour, this kind of neon city is often meant to feel cold and isolating, being designed for rich corporations rather than people.
- Hedonistic, glitzy, and/or sleazy: Neon signs are particularly associated with bars, casinos, motels, and other entertainment or tourist venues. As such, extravagant, flashing signage can be used to characterise a city as a place people go to have fun of the Viva Las Vegas! variety. Depending on the tone of the story, this might be good or bad — perhaps the city is an Absurdly Cool City full of genuine excitement and good times, or perhaps it's a superficial sham just trying to part you from your money. If the venues being touted are cheap and tawdry, like strip clubs and dive bars, it can establish a place as a Wretched Hive or a Vice City.
- Advanced: Filling a city with brightly coloured lights — or better yet, video screens and holograms — is sometimes used to make it look high-tech or intensively developed. Your average Cyberpunk city is often drenched in neon-esque lights (which stand out all the more if you've got typical cyberpunk weather and it always seems to be night-time). This use of neon may overlap with Tron Lines.
- Dated: In direct contrast to the previous, certain styles of neon are sometimes used to set a work in the past. For example, neon is sometimes associated with the vibrant colours of the The '80s and the New Wave era. If all the neon is golden-orange (the colour made by real, original neon), it can help set the work in the era before other colours became commonplace.
The neon city sometimes overlaps with City Noir, although those may be too grey to admit very much neon (and what there is will probably be showing Signs of Disrepair). See also Shining City (whose radiance is usually more metaphorical), Casino Park, and Cyberpunk with a Chance of Rain. Compare It's Always Mardi Gras in New Orleans, where the characters arrive at a big city at the one time of year with lots of bright flickering lights around. Some neon cities will consciously echo real-world cities known for their abundant bright signage, like Tokyo, Hong Kong, and Las Vegas.
(Note that, for the purposes of this trope, "neon" is defined broadly. Most "neon" lights don't actually use neon anymore, mostly being replaced by LED lights, but any bright city lights can be put to the same purpose.)
- Hetalia: Axis Powers: Briefly touched upon by Hong Kong in his image song "Hoi Sam☆Nice Guy", as he's the personification of one in real life; which variety of characterization he actually is is debatable, though his image songs hint that it's somewhere between hyper-capitalist, glitzy, and advanced.
Riding on a roofless bus, cruising through the neon streets
- One episode of Pokémon: The Series ("The Song of Jigglypuff") introduces the Vegas-like Neon Town, where the lights are always on and nobody seems to sleep. The Officer Jenny there has a notably short temper from being overworked.
- Yu Gi Oh ARCV: As the series takes place throughout four different dimensions, each of them has a different aesthetic to tell them apart, and create the proper atmosphere. The Synchro Dimension's "City" is a Crapsaccharine World, where 99% of the total wealth is controlled by only 1% of the population. The City has extremely high skyscrapers lit up so brightly that the night turns into day. It is even lampshaded.
Yugo: Beautiful, isn't it? How much wealth is in this skyline?
- Rock-A-Doodle has the villain send his Comic Relief nephew Hunch to thwart the heroes from contacting Chanticleer. Hunch is truculent, mentioning that the bright lights of the city will make him blind. The villain casually issues Hunch a pair of sunglasses. Truly, the big city is much brighter and busier than the rustic farmlands where the story originates. In fact, the heroes only found Chanticleer by noticing a huge neon likeness of him as an Elvis expy adorning Pinkie's nightclub.
- Spider-Man: Into the Spider-Verse uses this trope to good effect in the nighttime scenes.
- In Turning Red, Toronto is portrayed like this at night.
- Batman Film Series: Gotham City veered more towards such aesthetics in the Joel Schumacher films (Batman Forever and Batman & Robin) when compared to the city's dark part-gothic part-Art Deco aesthetics in the Tim Burton films.
- Blade Runner is often credited with establishing plentiful neon (preferably in the dark and the rain) as a central part of the Cyberpunk aesthetic.
- In Hiroshima Mon Amour, the bright lights of the new and rebuilt Hiroshima are used in a Contrast Montage with the female lead's hometown in France, which is full of old stone buildings.
- Only God Forgives was noted for going to town with neon. (One critic described it as an incoherent "neon-dunked nightmare", which was apparently meant as praise). The city in this case is Bangkok, which (at least for the main characters) is depicted as depraved and brutal.
- Taxi Driver uses the bright neon of Manhattan (including the famous Times Square) as a backdrop. It helps make Travis Bickle, who is almost completely disconnected from the world around him, seem even more of a sad loner.
- Osaka in Black Rain is full of neon lights; even the trucks driving around the city are covered in them. This makes Osaka look menacing and alien to the two NYPD detectives while they are in the city.
- Godzilla vs. Kong: The showdown between Godzilla and Kong takes place in Hong Kong, at night, amid skyscrapers bathed top to bottom in bright and colorful neon lights. Compared to the dreary, smoke-filled cityscapes featured in the previous two Godzilla movies, it comes across looking much more like a primetime wrestling match than a desperate battle for the fate of the planet.
- Last Clear Chance, (a Scare 'Em Straight driving safety film from 1959) warns about how distracting the neon signs of a big city can be to drivers. This includes a few shots demonstrating how easy it is to miss traffic lights or railroad crossing lights against a background of equally bright signage.
- Enter the Void takes place almost entirely at night in Tokyo, the ever-present neon lighting adding to the film's disorienting and hallucinogenic themes.
- The Canadian film noir Disappearance At Clifton Hill shows Niagara Falls, ON - especially the casino and the Clifton Hill neighbourhood, which is where a lot of the tourist traps are - to be this, definitely leaning more into the sleazy and dated aspects of this trope. Niagara Falls comes across as a tacky, seedy place.
- The opening sequence of The Howling has the heroine stalked through the neon-lit streets of early '80s L.A. by a Serial Killer. The rest of the film, however, is set in rural California and has a more Don't Go in the Woods aesthetic.
- This is the fate of Los Angeles after the Eruption and Long Winter in Agent G by C.T. Phipps. The city is rebuilt as an arcology with holograms, neon lights, and a Las Vegas meets Tokyo feel. It's such a dramatic change that the locals name it New Los Angeles after a few years.
- It continues in Sequel, The Cyber Dragons Trilogy, as New Los Angeles becomes even more an enormous Arcology of holographic billboards, neon signs, augmented reality projections, and lights on fashion as the world continues its slow recovery from the Eruption. Kei says she sometimes has to shut off her feed lest she suffer sensory overload.
- In Behind Blue Eyes, Olympias City is a massive city covering most of Western North America that is absolutely deluged in light based advertisements, glowing lights to keep it running twenty-four seven, and augmented reality. Since everything is owned by the Olympias Corporation, it is dedicated to keeping the public distracted by Bread and Circuses versus actual profit.
- Bubbles in Space has HoloCity that, as its name implies, is a place utterly deluged in advertisements and holograms that sell a bright materialist culture while distracting from the utterly miserable conditions the majority of the public live in. Pure water is, for example, an expensive luxury while brothels as well as purchase aps on your cybernetics are an eveyrday part of life.
- In Easytown, this is especially the case for the titular district of New Orleans. Being the Red Light District, it is full of holographic and neon signs advertising robot brothels, pornography dens, and specialized drug dens.
- In Episode 3 of Loki (2021), our main characters attempt to hijack a rocketship that is situated in the middle of a sprawling, crowded, futuristic city, with neon lights and paint decorating it.
- Simon & Garfunkel's "The Sound of Silence" uses neon imagery, although exactly what it means is probably subject to debate.
When my eyes were stabbed by the flash of a neon light
That split the night
And the people bowed and prayed
To the neon god they made
- A common aesthetic in the retrowave genres Vaporwave and Synthwave where cities at night with neon lights are used as part of the art-style as they were in The '80s and The '90s.
- Kraftwerk: "Neon Lights" from the album The Man-Machine is mostly instrumental, with the few lyrics being a tribute to the city's neon lights:
Shimmering neon lights
And at the edge of night
This city's made of light
- The Eagles: "In the City" has the depressing sort:
Somewhere out on that horizon
Out beyond the neon lights
I know there must be somethin' better
but there's nowhere else in sight
- Danny Elfman's "Cool City" from his 1984 album So-Lo never explicitly mentions neon, but definitely has the hedonism and hypercapitalism down:
Icy steel shoots through the concrete, Cool City
Mountains of glass reflect the sky, oh-oh-oh-oh-oh
Everybody feels real good in Cool City
Each day brings a new surprise, oh-oh-oh-oh-oh!
Johnny came two thousand miles to Cool City
He came to see what makes things tick, oh-oh-oh-oh-oh
He cut his hair and bought new clothes in Cool City
Finally found his life's ambition, oh-oh-oh-oh-oh!
How to do nothing perfectly
To do it with style so gracefully
'Cause life is so delicious here in Cool City...
If you're high you're in the right place, Cool City
Animals seek out their own kind, oh-oh-oh-oh-oh
Shake some hands and take a lunch in Cool City
Someone's going to try and tempt you, oh-oh-oh-oh-oh!
Listen to all the brilliant plans in Cool City
It's all free now, but you'll pay later with your soul

- L.A. Noire makes a certain amount of use of neon to help establish its time period — of particular note being its logo, which resembles a big, rooftop neon sign in traditional golden-orange.
- Dragon City in Loopmancer, supposedly a futuristic version of Hong Kong after two decades of non-stop technological growth and development. It has neon signs on buildings, rooftops, and even in the tunnels, and the cover art displays the city proudly in the foreground.
- Grand Theft Auto: Vice City goes for neon, including in its logo, as part of its 1980s Miami aesthetic.

- RUINER is set in the decidedly unpleasant city of Rengkok, where glaring red neon lights seem to be one of the main sources of illumination.
- Certain areas of Mass Effect have a more than a touch of neon to them, in keeping with the inspiration the series takes from 1980s-ish science fiction (which presumably includes a bit of cyberpunk, although the game as a whole doesn't fit that genre). On the Citadel, all the signage helps establish the place as a galactic crossroads; on Omega, it helps establish the place as a den of vice. The Silversun Strip◊ in the Citadel DLC is a wild riot of neon and holographic lights, immediately setting the tone that this is where everyone in the galaxy can come to party.
- Mario Kart:
- Mario Kart 7: One track in Star Cup, Neo Bowser City, has a futuristic theme which involves a lot of neon lights and bright displays (many of which serve to glorify Bowser). It was later added to Mario Kart 8 as DLC.
- Mario Kart Tour: Singapore Speedway portrays the eponymous capital of Singapore in this fashion, being raced on during a bright-sky night when all buildings show multi-colored lights and there's a more lively atmosphere. As with the other city-based tracks, it has three versions, each one taking place within a different part of the city. It was later added to Mario Kart 8 Deluxe as DLC, where all versions are combined into a multi-layered circuit.
- In Speed Kills, the final races are set on a capital planet which is full of bright, colourful signs, signalling that you've graduated from the various hell-holes you started on and are now in the big league.

- Fallout: New Vegas: Deliberately invoked by the titular city, New Vegas — a post-apocalyptic remnant of Las Vegas, Nevada. In the story, Vegas was left relatively untouched by nuclear bombardment during The Great War thanks to measures taken by billionaire Robert House. House has slept in cryogenic suspension for two centuries since then, until scouts from a new government called the New California Republic are spotted by House's robots. House awakens, immediately sends the robots out onto the Vegas strip to tame and force the roving savage tribes into helping rebuild the city in the spitting image of Vegas at its peak. By the time the NCR soldiers reach Vegas, they are entranced by the shimmering lights of a functioning city within the Mojave Wasteland and soon the city becomes a tourist attraction for NCR citizens, bringing House wealth and influence as part of his plans to rebuild civilization.
- Inkopolis from the Splatoon series is one of these (especially Inkopolis Plaza from the first game and Inkopolis Square from the second) in keeping with the series' emphasis on and the Inklings' and Octolings' loves of color, fashion, and pop-culture, and it gets even brighter and more colorful during a Splatfest. Downplayed with Splatsville from Splatoon 3 due to that installment's Desert Punk aesthetic, but there's still a fair amount of neon there, the player can switch between Splatsville and Inkopolis Plaza through DLC, and, as always, things get even more colorful than usual during a Splatfest.
- Cyberpunk 2077: Night City is littered with neon and holographic advertisements, as seen in the opening shots of the E3 2019 trailer.

- You'll be hard pressed to find a Sonic the Hedgehog game that doesn't have have a Neon City-like level. And even the rare few that don't tend to hold a neon light motif in at least one of their levels. Most have overlap with Casino Park—which itself was named after a stage in Sonic Heroes—but occasionally the concept is taken in another direction, such as Tropical Resort in Sonic Colors, which is one very large hotel area with no casino motifs whatsoever; and Mystic Jungle in Sonic Forces, which instead has neons combined with Ruins for Ruins' Sake.
- The Bonus Dungeon of Miitopia, New Lumos, is a neon-lit, perpetually rainy cyberpunk city populated by deadly monsters. Its name in the Japanese version is literally "Neon City".
- Battlezone (2016) takes place across various futuristic cityscapes with glowing neon light sources.
- Delight City in NiGHTS: Journey of Dreams manages to achieve this visual effect in the daytime by having most of its buildings and roads in nonreflective dark shades to contrast the bright glowing lights further.
- Pokémon Black and Pokémon Black 2 have Black City, which is full of tall buildings with Tron Lines on the floor and buildings. These games' version of Opelucid City have a similar look to them, though with smaller buildings and a more explicitly futuristic look. They're both part of the technology motif behind Black and Black 2, whereas White and White 2 have a nature motif.
- Hitman 3's End of An Era level takes place during a rainy night against the backdrop of a futuristic city, in the Yuzhong District of Chongqing. The neon lights here are positively brilliant.
- Ghostrunner's Dharma City is a shining example of this, being a massive skyscraper tower housing all of the remaining humans on Earth after a mysterious cataclysm known as The Burst. Jack, the player character, must ascend the city using elevators, and frequently wallruns on the sides of neon signs and screens.
- Cloudpunk is set in Nivalis, the last city on earth.

- SaGa Frontier Koorong features giant neon signs in the commercial area and functions as the closest thing the game has to a Hub City as its port is the only one that connects to most regions. The city has the undeniable atmosphere of a lawless, ungoverned place and posses amenities such a Black Market located in the sewers where you can buy goods that range from illegal drugs to military-grade equipment and a back alley clinic run by an extremely shady doctor.
- Some of the more urban stages in Overwatch are like this, in particular the Busan stage.
- Mirroria City in Tower of Fantasy is a thriving cyberpunk city full of bright neon signs floating on top of an apocalyptic desert populated with dangerous monsters. It used to be on the ground, but the harsh environment and invading Grayspace Entities wrecked their plans to repair the environment around the city and forced the people to make the city float in the sky.
- Paradise City from Turbo Overkill is filled with neon signs and colourful lights in every corner, but it's also loaded with synthetics out to Kill All Humans.

Then Marge reveals where they really are: "Well, he's not in the neon sign store."
- The titular Moonbeam City is a retrofuturistic Wretched Hive, all bathed in shades of purple and pink, where everyone dresses like it's The '80s but advanced enough to have rotating hotels, people with Artificial Limbs, and an ED-209 Expy. They also mine lasers, which somehow gush from the ground like oil.
