If you have Autometer electric gauges they used to make a device called 'Tri-Alert'.
You could setup any three gauges for either sound, light or both. I set mine up with a
dash light and a light that looks like a small shift light on top of the dash. This one is
removable as I only use it on the track.
I set up for high water temp, high
oil temp and low
oil pressure.
