Turn your iPhone or iPad into a working traffic signal. Signal Lights runs a real signal cycle on your screen, at whatever timings you set. Prop it up next to a play mat and it directs toy cars. Stand it on a desk and it teaches a child what amber actually means. Hold it up at a campsite gate or a classroom door and it does a job. CHOOSE THE SIGNAL YOU KNOW Signals are not the same everywhere. Some show red and amber together before green, as a get-ready; others go straight from red to green. Both are built in, along with a pedestrian crossing, a flashing amber for caution, and a simple stop-and-go with no amber at all. Pick whichever matches the signal outside your window — you will see it running as a small preview before you choose. SET YOUR OWN TIMINGS Every phase can be adjusted, and each signal remembers what you set. Change your mind and one tap restores the standard timings. TWO WAYS TO RUN IT Automatic runs the cycle on a timer, like a real signal. Manual waits for you — tap to change the light yourself, which is what you want when you are directing people rather than simulating traffic. BUILT TO BE SEEN In portrait you get the full signal head with the countdown inside it. Turn the phone sideways and the lit lamp fills the screen, large enough to read across a hall or a car park. The screen stays awake while the signal runs, and you can dim the app without touching your phone's own brightness. MADE TO BE READABLE BY EVERYONE A colour-blind-safe palette replaces red and green with tones that stay distinct, and turns on lamp names so the signal never depends on colour alone. An outdoor mode brightens everything for use in daylight. VoiceOver announces each change as it happens. PRIVATE BY DESIGN Signal Lights asks for no permissions. It does not use the camera, the microphone, Bluetooth or your local network, and it never connects to the internet. There are no accounts, no advertising, no analytics and no tracking of any kind. Nothing you do in the app leaves your device. It works exactly the same in aeroplane mode. — Signal Lights is a simulator and a teaching tool. It is not a traffic control device and must never be used to direct vehicles or people on public roads. ## Key features - Traffic light simulation - Customizable signal timing - Educational tool for children - Indoor game functionality - Standard green, amber, red signals ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/signal-lights/id1283323703/reviews.md ### 1/5 — You had ONE job *2022-01-15* This app shows you a red light, then a yellow, then a green. In that order. With no way to change the order. Comeon man. ### 3/5 — Fun app - but light sequence is backwards *2020-09-08* Great idea, but as previous reviewer said, the sequence should be: Red —-> Green —-> Yellow —-> Red —-> ### 3/5 — Good but reversed *2019-02-09* A fun little app that lets my little one run laps around the house! I like that intervals can be changed. One simple change needed: reverse the order of the lights. As it is currently, it goes: red, yellow, green, red... It needs to be changed to go: green, yellow, red, green... ## Frequently asked questions about Signal Lights ### What is Signal Lights used for?

They now stay put. THE PEDESTRIAN CROSSING Once the flashing "finish crossing" phase had run, the lamp kept flashing through the phases that followed. It now flashes only when it should. THE SEQUENCE LIST IS EASIER TO READ Text on the sequence screen was low contrast against the dark background. REPORT AN ISSUE OR REQUEST A FEATURE There is now a way to get in touch, under About & support. It opens your own mail app with a message ready to send — nothing is sent unless you send it. ### 2.0 — 2026-08-07 Signal Lights has been rebuilt from the ground up — the first update in a long time, and a thorough one. YOUR TIMINGS ARE NOW SAVED Previously the app forgot them every time you closed it. It doesn't any more. Each signal keeps its own timings, and a single tap restores the standard ones. MORE THAN ONE KIND OF SIGNAL Signals differ around the world. You can now choose one that shows red and amber together before green, or one that goes straight from red to green — plus a pedestrian crossing, a flashing amber, and a plain stop-and-go. Each is shown running as a small preview before you pick. TAP TO CHANGE THE LIGHT A new manual mode waits for you instead of running on a timer, for when you are directing people rather than simulating traffic. EASIER TO SEE Turn the phone sideways and the lit lamp fills the screen, readable from across a hall. In portrait, the countdown now sits inside the signal head. You can dim the app without changing your phone's brightness, and the screen stays awake while a signal runs. READABLE BY MORE PEOPLE A colour-blind-safe palette keeps red and green distinct and labels the lamps, so the signal never relies on colour alone. An outdoor mode brightens everything for daylight. VoiceOver now announces each change as it happens. NO ADVERTISING, NO TRACKING No advertising, no accounts, no analytics, no tracking, and no permissions requested. The app never connects to the internet. ### 1.0 — 2017-09-20 This app has been updated by Apple to display the Apple Watch app icon. ## Apps similar to Signal Lights | App | Rating | Price | Category | | --- | --- | --- | --- | | [艾码编程](https://appshunter.io/ios/app/id1499055820) | 5.0 (1) | Free | Entertainment | | [Urja Darpan](https://appshunter.io/ios/app/urja-darpan/id1501481160) | — | Free | Entertainment | | [NugSmasher®](https://appshunter.io/ios/app/nugsmasher/id1501395880) | 3.4 (24) | Free | Entertainment | | [Sary](https://appshunter.io/ios/app/sary/id1503182220) | — | Free | Entertainment | | [Music HouDai - stream player](https://appshunter.io/ios/app/music-houdai-stream-player/id1498728560) | 4.6 (9) | Free | Entertainment | | [Show Box Loca-Movie & TV Guide](https://appshunter.io/ios/app/show-box-loca-movie-and-tv-guide/id1499306740) | 4.0 (40) | Free | Entertainment | ## More apps by Jose Tomy Joseph - [Rivo](https://appshunter.io/ios/app/rivo/id6760328402) All apps by Jose Tomy Joseph: https://appshunter.io/developer/1090882701 ## Related topics [semaforo](https://appshunter.io/ios/topics/semaforo) · [traffic lights simulator](https://appshunter.io/ios/topics/traffic-lights-simulator) · [japanese traffic lights](https://appshunter.io/ios/topics/japanese-traffic-lights) · [kids traffic lights simulator](https://appshunter.io/ios/topics/kids-traffic-lights-simulator) · [traffic light](https://appshunter.io/ios/topics/traffic-light) · [traffic light kids](https://appshunter.io/ios/topics/traffic-light-kids) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
