<VV> Reasons for a buzzer.

[FrankCB]

Seth,
     That's why they call them "idiot lights".  They're for the idiots that drive cars without looking at the gauges, or without understanding what the gauge readings mean.  Obviously for a racer it's a different matter since his attention is completely absorbed by trying to "drive on the edge".

I agree, Mark - Of all of the 140 Corsas I have owned, none came with a   
buzzer. I installed it on a few of them. Here is an additional reason for the   
buzzer - and for maintaining your "Idiot" lights.  A friend bought a nice,  new 
1974 BMW 2002 (back in 1974). He ordered it with an optional VDO gage  package. 
Three beautiful gages in the middle of the dash. The gage pack replaced  the 
idiot lights, at least for the oil pressure. His wife was driving it once  and 
an oil cooler line came off. She was not watching the gage, no warning   
light, and cooked the inside of the motor. That is in street  driving where you 
should have plenty of time to watch the gages. Most racing  Corvairs I see, 
these-days, have a huge light (A trailer taillight works well)  mounted in/on the 
dash, hooked up to either the oil pressure sender (high  minimums suggested) 
the cooling fan indicator (which can be pressure or  idler-position fed) or head 
temp switches. Or to all three of them!  -  Seth
