White Screen for Light


Use this free online flashlight to turn a compatible phone's rear camera light into a torch or use the full screen as a bright flashlight. The built-in emergency SOS mode repeatedly sends the international Morse pattern of three short signals, three long signals and three short signals using screen light, sound and supported device vibration.

You can choose white, red, amber, green or blue screen light, change SOS speed and volume, enter a local emergency or trusted-contact number, request your current location and copy an emergency message with a map link.

Why the Camera Flashlight May Not Work

Camera access normally requires a secure HTTPS page and explicit permission. Even after access is allowed, some phones, desktop webcams and browsers do not expose continuous torch control. The tool checks the active video track's capabilities before applying the torch constraint and switches to screen light when needed.

Browser pages cannot directly force the device's system brightness setting. For the strongest screen light, increase display brightness manually, keep the page in full screen and point the screen toward the area that needs illumination.

Emergency notice: This browser tool is only an aid and does not contact emergency services automatically. In immediate danger, call the official emergency number for your current location. Flashing light may affect people with photosensitive epilepsy or other light sensitivity.
