I think the biggest improvement was making the oil warning led a
blinking warning to better get the driver's attention. The second oil
switch I agree is of debatable value except it allowed for a loud
warning buzzer to be added to really get the driver's attention while
driving. I might be happier with just a 1 switch setup if it was
combined with a buzzer that triggered whenever the warning light came on
while the engine was running. An oil pressure gauge is not a viable
substitute for a warning light but does its uses as an additional item
though I know of many people who added one only to have IT be the source
of trouble.
