The light in question is part of the warning system in the instrument cluster if you don't have a Tachometer, and it is in the center of the upper dashpad if you have a tach. It is controlled by the DRL module in either case. Power is supplied to it by the clock/radio fuse, and the DRL grounds the bulb circuit to turn it on, so even if your DRL are working properly, the lamp is not part of the operation, merely an indicator. If it flickers, then either the connection on the bulb or wiring is bad, or the DRL module itself is bad. In either case, take it to the dealer if under warranty or not. untrained people probing connections without the proper test equipment can EASILY short out more expensive components.
