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.
