Old news- - - -the 1964 White Freightliner I used to herd up and down the highways of California had a warning buzzer for oil pressure- - - -and coolant temperature- - - -and air brake pressure. About the only thing that didn't blink, buzz, or vibrate was the fuel gauge!

Trying to reinvent the wheel? I think that has been done a time or two also.
