O2 gauge and voltage readings...

I'm seeing something very wierd with my car. During the day the air/fuel gauge will cycle from bottom of red to top of orange, never going into green until boost.
Now, when I step on the brakes, the gauge doesn't read exactly the same. Instead of lighting up the last orange bar it drops down bar.
If I turn my lights on, the gauge drops 2-3 bars. I can watch this happen very easily by switching my lights on and off while it's at it's peak.
Now here's the crazy part...
I disconnected the gauge thinking it was bad and hooked up a voltmeter to the wire going into the ECU. It does the same thing. When I turn my lights on, the voltage drops from .75 to .70.
Any ideas?
I can only assume that this will affect my mixture. The wire is reading leaner so the ECU adds more fuel to compensate? Not good!
Maybe the saab ecu is really smart. Since it's dark out the air must be cooler than in the daytime, so it automatically richens the mixture!!! HA.
