Morse Code Light Translator
Opens a fullscreen flasher. On a phone you can use the camera torch instead of the screen. A photosensitivity warning appears first — flashing only starts when you press play.
Type a message and send it as flashing light. Your screen blinks the dots and dashes so you can signal across a room, a field, or a window — free and instant.
How to flash a message in Morse code
Enter your text and press Flash. The screen goes dark and then blinks: a short flash for each dot, a longer flash for each dash, with pauses between letters and words. Use the speed control to slow it down so it's easy to follow, and the brightness control to make it visible in bright or dark conditions. Press again to stop.
Use your phone's torch
On many phones, the tool can flash the camera light (torch) instead of the screen, which is far brighter and better for signalling outdoors or over distance. If your device and browser support it, you'll see a torch toggle — turn it on, then flash your message. If not, the screen flasher works everywhere.
Signalling ideas
Flashing light is how Morse code has been used at sea and between aircraft for over a century. You can use it to send a fun message to someone across the street, practice reading Morse by eye, or add a realistic signalling effect to a video or game. Start slow while you and your partner learn to read the rhythm, then speed up.
Frequently asked questions
How do I send Morse code with light? Type your message and press Flash. The screen (or phone torch) blinks the dots and dashes automatically.
Can it use my phone's flashlight? On supported phones and browsers, yes — enable the torch toggle. Otherwise the full-screen flasher works on any device.
Can I change how fast it flashes? Yes. Use the speed slider to set the words-per-minute rate.
