Day time running lights work, high beams work, but low beams don't work. When both low beam bulbs are taken out of sockets, and sockets are tested with test light, both prongs on both sockets light up the test light. When one bulb is taken out, only one plug lights up. No low beam head lights work, only on day time running lights.

Are you making a statement or are you asking a question?
If you are trying to diagnose the condition that you are describing, you will need to measure voltage with a volt meter because daytime running lights (DRL) run at reduced voltage. A test light will not provide enough information. Has the car ever been in an accident? Are there any aftermarket accessories like a security system, remote starter, audio system, fog lights, i-Pod adapter, etc. installed?
When you get a voltage meter, preferably a volt-ohm meter, you can check the actual voltage at the headlight plugs and you can also check the operation of the combination switch and the light sensor.
Thanks for the clarification and for sharing what fixed the problem!
