Reply to "Tachometer Light"

The red lights at the bottom of most VDO tachs that we have in our Speedsters are warning lights. The left one is alternator/generator output which in a VW Type 1 engine could mean your fan belt has come off which is bad, bad, bad, The right light warns of low oil pressure. Both should illuminate when the ignition key is turned on and then go off and stay off once the engine starts.  Does the light come on when your engine is at idle? If so you possibly have a low oil pressure issue. Could be a sign of a worn out engine among other things.
