It should light for seven seconds after turning on the ignition switch. It goes out when all the self tests are passed. It should never turn on while driving. If it does, the computer detected an electrical problem and set a diagnostic fault code. Having that code read will get you into the circuit that needs further diagnosis. The system is turned off and the bag will not deploy when the light is on.
