Sue Hanna, What do you mean by this? Do you mean when your Tachometer revs to the 6-8 range, the lights go red? or are they going on all the time? Is this something that just started?

Red goes to the ignition switch fuse for power in the fuse box green goes to the the negative side of the distributor white is for the tachs light so it will go to the dash light fuse in the fuse box and black is for the ground.

HERE IS A LINK TO A WIRE DIAGRAM! THE GREEN GOES TO THE NEGATIVE SIDE OF THE COIL. GOOD LUCK!

This is prolly a chevy and that light is just that a low water level indicator it is saying check your cooliant level. Add anti-freeze not water or you may crack your radiator as it gets colder out.

If I'm right, and this vehicle is a stick, this model has shift indicator lights. Green arrow points up when its time to shift up, and red arrow points down when you need to downshift. If it does, the tach, which registers the motor rpm's, which controlls the lights, is malfunctioning.

factory sealed by law brother, pay the man

According to wiring diagrams online... good luck with this.

It sure sounds like one of many possibilities but it might have something to do with your coil ...
