A warning light comes on, you are already moving, and the manual is not in the glovebox. Point your camera at the symbol. Signal tells you which light it is, how serious it is, and whether it is safe to keep driving. No dongle. No plugging anything into the port. No scrolling a grid of sixty icons hoping one of them matches. WHY THIS IS DIFFERENT Every other dashboard reference makes you look the symbol up by name. That inverts the problem โ€” if you knew what it was called, you would not need the app. Signal turns the camera into the search box. WHAT YOU GET Identify any light from a photo Point, shoot, and get the symbol named in plain English, with what it actually means for your car. A straight answer on whether to drive Every result is coded red, amber or green, the same way your dashboard codes them. Stop the car, service soon, or nothing urgent โ€” plus what to check right now. The full symbol reference, offline Every standard warning light is stored on your phone. It works on a hard shoulder with no reception, and it is free with no limit. Common causes, ranked The handful of things that usually cause this light, so you can check the cheap one first. A loose fuel cap costs nothing to rule out. A garage that remembers Every scan is filed against the car it came from, with the date, so you can see whether that light has been back. FREE AND PREMIUM Free gives you the complete offline symbol reference with no limit, two camera identifications, full severity verdicts, and one vehicle. Signal Premium adds unlimited identifications, typical repair cost ranges so nobody quotes you blind, and every car you look after in one place. BEFORE YOU RELY ON IT Signal explains what your dashboard is showing you. It is information, not an inspection, and it cannot see anything the lamp is not telling it. If the car feels wrong โ€” noises, smells, smoke, or a change in how it drives โ€” stop and get it looked at, whatever the app says.
