Idiot light extinguishes at about 5 psi (say). It tells you your engine is
broken and suggests that if you don't want it broken worse you should stop
very very soon. Good as a final warning if you're too busy to occasionally
check on the gauges or for that time when you punch a hole in the sump and
loose all the oil.
