| On some models, ST4S, that is the oil pressure warning light. Where it's not used, there isn't usually a bulb in there.
Is the LED in the Tacho going out? That's the normal pressure warning light.
Might be worth checking the pressure switch isn't bust. If that checks out, then looks like you've got a wiring gremlin.
One last thought...........it's also a favourite for the alarm LED to get positioned. Is the alarm, if fitted, in service mode or something??? |
