01 Corolla head lights

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.

I guess I should have been a little more direct, but thanks, we solved
the problem, it was a ground problem with the dimmer relay, this is
kind of my first time using this board. We just had to stop for a sec,
have a smoke and talk it through with one another.
