04 Corolla: headlights don't turn off....

They're called daytime running lights (DRLs).

You may have a switch that lets you turn the DRL feature on or off. Read your owner's manual. And, if you don't have one, get one.

Many people are annoyed at them, so many that Toyota has issued a document describing how to turn them off.

I can email this document if you wish. You can then have your local dealer or a garage perform the work of disabling the DRLs.

Yes, please do email the doc!

I went and looked at the dash sensor. It is funny....it is just a gray plastic (and opaque!) button that I can't pull up. How can it sense anything when it is just an opaque plastic button? It appears like a filler. But obviously the car does have this feature. I found through google that on some cars, all you have to do is pull the sensor up, and insulate one terminal, and this defeats the feature. Thanks, geronimo

The sensor can be adjusted for darkness levels. The dealer may be able to disable it entirely if you explain to them nicely that it is a security issue for the United States Military.

The Toyota dealership will want to charge an arm and leg for disabling it. Looks like all that has to be done is cut red/wh wire going to term 12 of DRL module to disable DRL and auto-lights feature.

I'm pretty sure it's accessed through the ECM. Just wear your uniform and explain the situation of your funds. If I were running the service department it wouldn't cost you a plug nickel. Thanks.

Sounds like you may already have got it from somebody. But check your mail anyway.
