Would take a bit of digging thru the parts books at NAPA but you should be able to find a sending unit that is set to come on at a more useful low psi. Have never understood the oil light coming on when you are at a dangerously low pressure. By then it is usually to late. If it were to come on at say 5psi over what the factory one is set for it very well might make the difference between a locked up paper weight and a still running motor....
