Board indicator

I have a standard Focus 2002, an orange signal that looks like a helm with a sign of admiration inside, when I stopped, I feel that it loses current, but as I go at speed flashes and turns off and turns off and goes out

Greetings friend, the symbol of the light that you describe is called as a warning light of the motor systems, that is that you possibly have a failure in the electrical system of the engine, as it could be a current cut in the coil, in sensors or ajectors, I recommend that you go with an automotive technician to check your vehicle friend, luck.
